Za'ba menegaskan bahawa kemiskinan orang Melayu bukan semata-mata akibat penjajahan atau faktor luaran, tetapi berpunca daripada kelemahan dalaman masyarakat itu sendiri.  Antara faktor yang dikupas:

Sikap pasrah dan fatalistik: Penerimaan kemiskinan sebagai takdir yang tidak boleh diubah, sering disandarkan pada tafsiran agama yang sempit. 

Kelemahan daya usaha: Kurangnya semangat untuk bekerja keras, menuntut ilmu, dan mengambil risiko dalam bidang ekonomi. 

Ketergantungan: Sikap bergantung kepada bantuan luar tanpa usaha untuk berdikari. 

Amalan hidup boros: Pembaziran dalam adat dan kenduri yang membebankan kewangan keluarga. 

Kecelaruan nilai agama: Pemahaman agama yang menghalang kemajuan duniawi dan menolak usaha sebagai sesuatu yang penting. 

2. Cadangan Jalan Kepulihan

Za'ba mencadangkan beberapa langkah reformasi untuk mengangkat masyarakat Melayu daripada kemiskinan: 

Perubahan sikap dan pemikiran: Menanamkan keyakinan diri, pemikiran kritis, dan semangat berdikari. 

Pendidikan moden: Menggalakkan pendidikan dalam bidang sains, teknologi, dan ekonomi serta latihan kemahiran praktikal. 

Pemerkasaan ekonomi: Mendorong penglibatan dalam perniagaan dan pengurusan kewangan yang bijak. 

Pengukuhan institusi: Membentuk kepimpinan yang berwibawa dan organisasi sosial seperti koperasi untuk membantu masyarakat secara kolektif. 

Penafsiran semula agama: Menggalakkan pemahaman agama yang progresif dan menolak fatalisme.

U.S. Nuclear Regulatory Commission (NRC)

U.S. Nuclear Regulatory Commission (NRC)

The U.S. Nuclear Regulatory Commission (NRC) is an independent federal agency responsible for ensuring the safe use of nuclear materials in the United States. Its mission is to protect public health and safety, promote the common defense and security, and protect the environment by regulating nuclear reactors, materials, and waste.

---

1. History and Formation

The NRC was established on January 19, 1975, as a result of the Energy Reorganization Act of 1974. This act split the Atomic Energy Commission (AEC) into two separate agencies:

• The NRC – Focused on regulation and safety of nuclear materials.
• The Energy Research and Development Administration (ERDA) – Later merged into the U.S. Department of Energy (DOE), focusing on nuclear energy research and development.

Before the NRC, the AEC both promoted nuclear power and regulated it, creating a conflict of interest. The NRC was created to ensure an independent regulatory focus.

---

2. NRC Organizational Structure

The NRC is led by a five-member commission appointed by the President of the United States and confirmed by the U.S. Senate. One of these commissioners is designated as the Chairperson.

Key Leadership Positions:

Orang biasa mengetahui LOTS (Lower Order of Thinking Skills – Kemahiran Pemikiran Aras Rendah). Ini merujuk kepada tahap pemikiran asas yang lebih bersifat hafalan dan pemahaman mudah.

Orang cerdik mengetahui HOTS (Higher Order of Thinking Skills – Kemahiran Pemikiran Aras Tinggi). Ini merujuk kepada pemikiran kritis, analisis, dan kreativiti dalam memahami sesuatu.

Hanya segelintir orang yang bijaksana memahami dan mengamalkan DOTS, yang merupakan tahap tertinggi dalam pemikiran, iaitu pemahaman yang mendalam dan kebijaksanaan sebenar.

Etimologi Intelektual: Perjalanan Manusia Mencari Ilmu

(Sumber rujukan: Muhammad Ibn Muhammad Ibn Muhammad Ibn Ahmad al-Tusi)

Dalam perjalanan intelektual seseorang, terdapat tiga peringkat utama:

1. LOTS (Lower Order Thinking Skills) – Hati Mati

Hati yang mati melambangkan seseorang yang hanya memahami ilmu secara permukaan tanpa mendalami maksud atau hikmah di sebaliknya.

Ini merujuk kepada pemikiran yang hanya bergantung kepada fakta tanpa refleksi yang mendalam.

2. HOTS (Higher Order Thinking Skills) – Hati Hidup

Hati yang hidup melambangkan seseorang yang mula memahami dan menggunakan ilmu secara lebih mendalam.

Pemikiran mereka lebih analitikal dan kreatif, membolehkan mereka menyelesaikan masalah dan membuat keputusan yang lebih baik.

3. DOTS – Hati Bersinar (Luminance Heart)

Ini adalah tahap tertinggi dalam intelektualiti dan kerohanian.

Seseorang di peringkat ini bukan sahaja memiliki ilmu dan pemikiran kritis tetapi juga kebijaksanaan sejati yang diterapkan dalam kehidupan.

Mereka memahami makna yang lebih mendalam dalam ilmu dan menggunakannya dengan cara yang memberi manfaat kepada diri sendiri dan masyarakat.

Kesimpulan

Gambar ini menggambarkan perjalanan seseorang dalam mencari ilmu, dari sekadar mengetahui maklumat asas (LOTS), kepada memahami dan mengaplikasikan ilmu dengan lebih mendalam (HOTS), sehingga mencapai tahap kebijaksanaan yang benar dan memberi cahaya kepada kehidupan (DOTS).

Konsep ini juga boleh dikaitkan dengan perjalanan seseorang dalam meningkatkan tahap keimanan dan ketakwaan kepada Allah, di mana ilmu yang sebenar bukan hanya dihafal tetapi difahami dan diamalkan dalam kehidupan seharian.

How to solve overthinking.

Overthinking can be mentally exhausting and unproductive. Here are some effective strategies to manage and reduce overthinking:

1. Identify Triggers

Notice situations, thoughts, or emotions that lead to overthinking.

Keep a journal to track recurring patterns.

2. Set Time Limits for Decisions

If making a decision, set a specific time (e.g., 10–15 minutes) to analyze options and then move forward.

Avoid perfectionism; make the best choice with the available information.

3. Engage in Mindfulness & Meditation

Practice deep breathing exercises or guided meditation to stay present.

Focus on what you can control instead of dwelling on uncertainties.

4. Reframe Negative Thoughts

Replace "What if I fail?" with "What if I succeed?"

Instead of "I can’t handle this," think, "I’ll handle it step by step."

5. Take Action

Overthinking often delays action. Break tasks into small steps and start with the easiest one.

Action reduces uncertainty and builds confidence.

6. Limit Information Consumption

Too much information can lead to analysis paralysis.

Focus on essential facts rather than endless research.

7. Use the 5-Second Rule

Count "5-4-3-2-1" and then immediately act on the thought or decision to break the overthinking cycle.

8. Exercise Regularly

Physical activity releases stress and boosts mental clarity.

Even a short walk can shift your focus away from overanalyzing.

9. Talk It Out

Discussing your thoughts with a trusted friend or mentor can offer new perspectives.

Sometimes, verbalizing a problem helps to realize it's not as big as it seemed.

10. Set Worry Time

Schedule 10–15 minutes daily to think about concerns. If worries arise outside this time, remind yourself to "save it for later."

11. Practice Self-Compassion

Accept that mistakes are part of growth.

Avoid self-criticism and focus on learning from experiences.

12. Distract Yourself

Engage in hobbies, listen to music, or read a book to shift focus.

Overthinking thrives in idleness, so stay occupied.

Ramadhan #1 - Sifat Mahmudah vs Sifat Mazmumah

Ikhlas vs Riya': Perbezaan dan Implikasinya

Ikhlas merupakan salah satu sifat mahmudah (terpuji) yang sangat penting dalam kehidupan seorang Muslim. Ia bermaksud melakukan sesuatu semata-mata kerana Allah tanpa mengharapkan sebarang balasan atau pujian daripada manusia. Sifat ini melahirkan keikhlasan hati dalam setiap amalan, menjadikan seseorang lebih tenang dan jauh daripada perasaan ingin menunjuk-nunjuk. Sebaliknya, riya’ ialah sifat mazmumah (tercela) yang merosakkan keikhlasan seseorang. Ia merujuk kepada perbuatan yang dilakukan bukan kerana Allah, tetapi untuk mendapatkan pengiktirafan atau pujian daripada manusia. Riya’ bukan sahaja menghilangkan keberkatan dalam amal ibadah, malah boleh membawa kepada kemurkaan Allah.

Maksud dan Kepentingan Ikhlas

Ikhlas berasal daripada perkataan Arab "ikhlās" yang bermaksud suci atau bersih. Dalam konteks Islam, ia merujuk kepada kesucian niat dalam setiap perbuatan, sama ada dalam ibadah, pekerjaan, atau urusan seharian. Ikhlas memastikan bahawa segala amalan diterima oleh Allah, sebagaimana firman-Nya dalam Surah Al-Bayyinah ayat 5:

"Dan mereka tidak diperintahkan melainkan supaya menyembah Allah dengan ikhlas dalam menjalankan agama yang lurus..."

Sifat ikhlas memberikan ketenangan jiwa dan mengelakkan seseorang daripada rasa kecewa jika tidak mendapat penghargaan daripada manusia. Orang yang ikhlas juga lebih fokus kepada usaha mereka kerana mereka yakin bahawa ganjaran sebenar datang daripada Allah, bukan daripada makhluk.

Maksud dan Bahaya Riya’

Riya’ berasal daripada perkataan Arab "ra`ā" yang bermaksud melihat atau memperlihatkan. Dari segi istilah, riya’ merujuk kepada sikap menunjuk-nunjuk dalam beribadah atau melakukan kebaikan demi mendapatkan pujian manusia. Sifat ini merupakan salah satu bentuk syirik kecil kerana ia menggantikan niat yang sepatutnya hanya untuk Allah dengan niat untuk mencari perhatian manusia.

Dalam sebuah hadis, Rasulullah SAW bersabda:

"Sesungguhnya perkara yang paling aku takuti terhadap kamu ialah syirik kecil." Para sahabat bertanya, "Apakah syirik kecil itu, wahai Rasulullah?" Baginda menjawab, "Riya’." (Hadis Riwayat Ahmad)

Riya’ boleh muncul dalam pelbagai bentuk. Contohnya, seseorang mungkin bersolat dengan penuh khusyuk apabila berada di hadapan orang ramai tetapi melakukannya secara sambil lewa ketika bersendirian. Ada juga yang bersedekah tetapi menghebahkannya supaya orang lain mengetahui. Sifat ini bukan sahaja menghilangkan pahala, malah boleh menyebabkan hati menjadi tidak tenang kerana sentiasa mengharapkan pengiktirafan daripada manusia.

Cara Menghindari Riya’ dan Memupuk Ikhlas

1. Memperbetulkan niat – Sebelum melakukan sesuatu, individu perlu bertanya kepada diri sendiri sama ada ia dilakukan kerana Allah atau kerana manusia. Jika ada unsur riya’, segera perbetulkan niat.
2. Menyembunyikan amal kebaikan – Seboleh mungkin, elakkan daripada menghebahkan amal kebaikan yang dilakukan, kecuali dalam keadaan yang boleh menjadi contoh kepada orang lain tanpa niat menunjuk-nunjuk.
3. Berdoa kepada Allah – Mohon perlindungan daripada sifat riya’ dengan berdoa, seperti doa yang diajarkan oleh Rasulullah SAW:
   "Ya Allah, aku berlindung kepada-Mu daripada syirik yang aku sedari dan aku memohon keampunan-Mu atas apa yang aku tidak sedari."
4. Mengingati bahawa pujian manusia tidak berkekalan – Pujian manusia hanyalah sementara, sedangkan ganjaran daripada Allah adalah kekal. Oleh itu, seseorang harus lebih mementingkan pandangan Allah daripada pandangan manusia.

Kesimpulan

Ikhlas dan riya’ merupakan dua sifat yang bertentangan, dengan ikhlas membawa keberkatan dan riya’ membawa kehancuran kepada amal ibadah seseorang. Sifat ikhlas menjadikan kehidupan lebih tenang kerana seseorang tidak bergantung kepada pengiktirafan manusia. Sebaliknya, riya’ menyebabkan seseorang hilang pahala dan hidup dalam ketidakpuasan kerana sentiasa mengharapkan pujian. Oleh itu, setiap individu harus berusaha untuk menanamkan keikhlasan dalam hati dan menjauhi sifat riya’ agar amalan mereka diterima oleh Allah serta membawa kebaikan di dunia dan akhirat.

BIOS Programming Language

The BIOS (Basic Input/Output System) is typically programmed using low-level languages because it interacts directly with hardware and needs to run before an operating system is loaded. The most common languages used for BIOS development are:

1. Assembly Language (x86 Assembly)

• Used for low-level hardware control and initialization.
• Essential for early boot stages before higher-level languages can be used.
• Example: BIOS interrupt calls (INT 13h for disk access, INT 10h for display control).

2. C Language

• Used for more complex parts of the BIOS after the system has initialized enough hardware to support C execution.
• Provides better readability and maintainability compared to Assembly.
• Most modern BIOS/UEFI firmware is written in C.

3. UEFI BIOS – C and Assembly

• Modern BIOS implementations use UEFI (Unified Extensible Firmware Interface) instead of traditional BIOS.
• UEFI is primarily written in C with some Assembly for low-level hardware setup.
• It follows the UEFI specification, which is typically implemented using EDK2 (EFI Development Kit 2), an open-source UEFI firmware development environment.

4. Scripting Languages for BIOS Configuration

• Python, Perl, and Lua are sometimes used for BIOS testing and configuration automation.
• Not used in the BIOS firmware itself but for development and debugging purposes.

Firmware Development Tools

• TianoCore (EDK2): Open-source implementation of UEFI firmware.
• GCC, LLVM/Clang, and Microsoft Visual Studio: Common compilers used for UEFI firmware development.

In summary, traditional BIOS firmware is mainly written in Assembly and C, while modern UEFI firmware is almost entirely written in C with minimal Assembly for early-stage initialization.

The primary computer languages used to design chips (integrated circuits)

The primary computer languages used to design chips (integrated circuits) are:

1. Hardware Description Languages (HDLs)

These languages are specifically designed to describe and model electronic circuits at various levels of abstraction.

3. High-Level Synthesis (HLS) Languages

C, C++, SystemC

Used in High-Level Synthesis (HLS) to convert high-level algorithmic descriptions into hardware designs.

SystemC is commonly used for system-level modeling.

4. Low-Level Programming for Chip Verification & Testing

Python, Perl, TCL, and Shell Scripting

Used for automation, verification, and testing of chip designs.

C & Assembly Language

Used for embedded systems and firmware development.

5. Analog and Mixed-Signal (AMS) Design Languages

SPICE (Simulation Program with Integrated Circuit Emphasis)

Used for simulating analog circuits and mixed-signal designs.

Verilog-AMS & VHDL-AMS

Used for designing circuits that involve both analog and digital components.

6. AI and Machine Learning for Chip Design

Python (TensorFlow, PyTorch) & MATLAB

Used in AI-driven chip design automation and optimization.

Each of these languages plays a critical role in different stages of chip design, from architecture definition to physical layout and verification.

Sekatan Teknologi ke Atas China Tidak Berkesan.

Pendahuluan.

Sekatan teknologi yang dikenakan oleh Amerika Syarikat (AS) ke atas China, terutamanya dalam eksport cip komputer berteknologi tinggi, sering dianggap sebagai strategi untuk mengekang kemajuan teknologi negara tersebut. Namun, kejayaan syarikat kecerdasan buatan (AI) China, **DeepSeek**, dalam menghasilkan model bahasa besar (LLM) yang kompetitif meskipun menghadapi sekatan, membuktikan bahawa langkah ini tidak berkesan. Malah, sekatan tersebut telah mencetuskan gelombang inovasi tempatan di China, mengubah halangan menjadi peluang untuk membangunkan teknologi alternatif yang lebih efisien.  

Kejayaan DeepSeek Menembusi Sekatan.

DeepSeek, syarikat AI yang berpangkalan di Hangzhou, berjaya mencipta **R1**, sebuah chatbot yang setanding dengan produk AS seperti ChatGPT, tetapi dengan kos pembangunan yang jauh lebih rendah (hanya AS$5.6 juta). Kejayaan ini dicapai meskipun AS menghalang akses China kepada cip terkini seperti H100 melalui sekatan eksport. Sebaliknya, DeepSeek menggunakan cip H800—versi lama yang masih dibenarkan dieksport sehingga akhir 2023—untuk melatih model AI mereka. Menurut pakar seperti Jeffrey Ding dari Universiti George Washington, sekatan ini memaksa syarikat China untuk mencipta algoritma lebih efisien, mengurangkan kebergantungan pada kuasa pengiraan tinggi. Ini menunjukkan bahawa sekatan teknologi tidak menghalang inovasi, malah mendorong pendekatan lebih kreatif.  

Polisi Sekatan Menjadi Pemangkin Inovasi China

Kisah kejayaan DeepSeek bukanlah yang pertama. Sebelum ini, syarikat gergasi teknologi China, **Huawei**, telah bangkit semula selepas sekatan AS dengan mengalihkan fokus kepada pembangunan sistem operasi HarmonyOS dan cip buatan sendiri. Polisi sekatan AS, yang bertujuan melambatkan kemajuan China, sebaliknya mencetuskan "kesan Sputnik"—istilah yang merujuk kepada kejutan teknologi Soviet pada 1957—di mana China membuktikan kemampuan mereka untuk mengejar bahkan menyaingi teknologi Barat. Seperti yang diakui Marc Andreessen, seorang pelabur terkemuka, kejayaan DeepSeek adalah "detik Sputnik" bagi AS, mendedahkan jurang strategi sekatan yang selama ini dianggap kukuh.  

Keterbatasan Sekatan dan Respons AS

 

Walaupun sekatan dilaksanakan untuk melindungi kepentingan teknologi AS, ia gagal menyekat kemajuan China dalam bidang AI. Malah, pakar seperti Samm Sacks dari Universiti Yale menegaskan bahawa kejayaan DeepSeek "menggugat anggapan lama" tentang keperluan kuasa pengiraan dan data yang besar untuk inovasi AI. Sebagai tindak balas, pentadbiran AS kini terpaksa mempertimbangkan langkah lebih radikal, seperti memperluas sekatan cip atau meningkatkan pelaburan domestik. Namun, seperti yang diingatkan Rebecca Arcesati dari MERICS, sekatan defensif semata-mata mungkin hanya akan mendorong lebih banyak negara untuk menyokong ekosistem AI China.  

Penutup

Sekatan teknologi AS ke atas China jelas tidak mencapai matlamat asalnya. Sebaliknya, ia menjadi pemangkin kepada inovasi tempatan yang lebih mampan dan efisien. DeepSeek dan Huawei adalah bukti nyata bahawa sekatan bukanlah penyelesaian untuk mengekang kemajuan teknologi sesebuah negara. Sebaliknya, AS perlu mengimbangi strategi dengan memperkukuh daya saing domestik sambil mengelakkan langkah yang boleh mencetuskan perlumbaan teknologi yang tidak sihat. Dalam dunia yang saling berkait, kerjasama dan persaingan sihat mungkin lebih efektif daripada sekatan sepihak yang hanya melahirkan lebih banyak "detik Sputnik".  

Rumusan

Kegagalan sekatan AS dalam menghalang kemajuan teknologi China mengajar kita bahawa inovasi tidak dapat dibendung melalui halangan politik. Sejarah membuktikan bahawa teknologi bersifat universal—sekatan hanya mempercepatkan proses penyesuaian dan kreativiti. Bagi mengekalkan kepimpinan global, negara perlu fokus pada pembangunan kapasiti sendiri, bukan sekadar menyekat kemajuan pihak lain.

Temubual dengan pendiri DeepSeek

**Bahagian 1: Persaingan Harga dan Jurang Teknologi**  

**Waves:** Dari luar, pemotongan harga kelihatan seperti usaha merebut pengguna, seperti yang biasa berlaku dalam perang harga era internet.  

**Liang Wenfeng:** Merebut pengguna bukan tujuan utama kami. Kami menurunkan harga kerana, pertama, kos kami menurun semasa meneroka seni bina model generasi seterusnya. Kedua, kami percaya API dan AI perlu diakses dan mampu dimiliki oleh semua.  

**Waves:** Sebelum ini, kebanyakan syarikat China menggunakan seni bina Llama untuk aplikasi. Mengapa anda mula dari struktur model?  

**Liang Wenfeng:** Jika tujuannya hanya untuk aplikasi, menggunakan Llama adalah masuk akal. Tetapi destinasi kami ialah AGI (Kecerdasan Umum Buatan), jadi kami perlu mengkaji struktur model baru untuk mencapai keupayaan lebih tinggi dengan sumber terhad. Ini asas untuk model lebih besar. Selain itu, kecekapan latihan dan kos inferens Llama dianggarkan ketinggalan dua generasi berbanding teknologi antarabangsa.  

**Waves:** Dari mana jurang generasi ini berasal?  

**Liang Wenfeng:** Pertama, jurang kecekapan latihan. Keupayaan terbaik China mungkin memerlukan dua kali ganda kuasa pengiraan untuk hasil sama seperti teknologi antarabangsa. Kedua, jurang kecekapan data: kami perlu dua kali ganda data dan kuasa pengiraan. Gabungannya, kami perlukan empat kali ganda kuasa pengiraan. Tugas kami ialah menutup jurang ini.

**Bahagian 2: Jurang Sebenar Bukan 1-2 Tahun, Tetapi Inovasi vs. Tiruan**  

**Waves:** Mengapa DeepSeek V2 mengejutkan Silicon Valley?  

**Liang Wenfeng:** Mereka terkejut kerana syarikat China menyertai permainan inovasi. Kebanyakan syarikat China hanya ikut trend, bukan mencipta.  

**Waves:** Tapi inovasi di China sangat mahal. Mengapa anda fokus pada penyelidikan, bukan komersialisasi?  

**Liang Wenfeng:** Kos inovasi tinggi, tetapi masalah China bukan kekurangan modal, tetapi keyakinan dan cara mengatur bakat untuk inovasi berkesan. Ekonomi China cukup besar—kini masanya untuk menyumbang, bukan sekadar menumpang.  

**Waves:** Syarikat gergasi seperti ByteDance dan Tencent lebih utamakan komersialisasi. Mengapa?  

**Liang Wenfeng:** Selama 30 tahun, kami hanya fokus pada keuntungan, mengabaikan inovasi. Inovasi memerlukan rasa ingin tahu dan hasrat mencipta—ini berkait dengan tahap ekonomi tertentu.  

**Waves:** Bagaimana anda membina "parit" (kelebihan kompetitif) jika inovasi anda dibuka sumber?  

**Liang Wenfeng:** Parit tertutup hanya sementara. Nilai kami terletak pada pasukan—rakan sekerja berkembang, mengumpul pengetahuan, dan membentuk budaya inovasi. Ini parit sebenar kami.

**Bahagian 3: Lebih Banyak Pelaburan ≠ Lebih Banyak Inovasi**  

**Waves:** Adakah anda akan tutup sumber seperti OpenAI?  

**Liang Wenfeng:** Tidak. Kami percaya ekosistem teknikal kuat lebih penting.  

**Waves:** Ada rancangan pembiayaan atau IPO?  

**Liang Wenfeng:** Tiada rancangan pembiayaan jangka pendek. Masalah utama kami bukan modal, tetapi sekatan cip AS.  

**Waves:** Kenapa tidak fokus pada aplikasi?  

**Liang Wenfeng:** Tahap ini adalah ledakan inovasi teknologi, bukan aplikasi. Kami ingin cipta ekosistem di mana industri gunakan teknologi kami. Jika perlu, kami boleh bangunkan aplikasi, tetapi keutamaan tetap pada inovasi.  

**Waves:** Mengapa pelanggan pilih DeepSeek berbanding syarikat besar?  

**Liang Wenfeng:** Masa depan akan ada pembahagian tugas khusus. Syarikat besar mungkin tidak paling sesuai untuk inovasi berterusan.

**Bahagian 4: Pasukan Muda dengan Budaya Inovasi**  

**Waves:** Siapa di sebalik DeepSeek V2?  

**Liang Wenfeng:** Kebanyakannya graduan universiti terkemuka, calon PhD, dan anak muda berusia 20-an. Tiada "ahli silap mata"—hanya bakat tempatan yang dilatih sendiri.  

**Waves:** Bagaimana inovasi MLA tercetus?  

**Liang Wenfeng:** Idea berasal dari minat peribadi penyelidik muda. Proses pelaksanaan mengambil masa berbulan dengan kerjasama pasukan.  

**Waves:** Bagaimana struktur pengurusan longgar ini berfungsi?  

**Liang Wenfeng:** Semua boleh akses GPU atau bekerjasama tanpa hierarki. Kami cari bakat berasaskan semangat dan rasa ingin tahu—bukan pengalaman tradisional.  

**Waves:** Adakah inovasi bergantung pada nasib?  

**Liang Wenfeng:** Inovasi bermula dengan keyakinan. Lembah Silikon berani mencuba—di China, keyakinan ini kurang. Kami percaya generasi muda akan ubah ini.

**Bahagian 5: Semua Kaedah Lama Akan Usang**  

**Waves:** Apa fokus utama anda kini?  

**Liang Wenfeng:** Menyelidik model generasi seterusnya. Masih banyak masalah belum selesai.  

**Waves:** Bagaimana dengan model keuntungan masa depan?  

**Liang Wenfeng:** Corak perniagaan lama tidak relevan. Bincang model keuntungan AI dengan logik internet seperti "menjual ais semasa Zaman Batu"—ia tidak berguna.  

**Waves:** Adakah ekonomi lemah akan sekat penyelidikan asas?  

**Liang Wenfeng:** Tidak. Penstrukturan semula industri China akan lebih bergantung pada inovasi teknologi. Apabila peluang cepat kaya hilang, orang akan lebih fokus pada inovasi sebenar.  

**Liang Wenfeng (kesimpulan):**  

"Saya dibesarkan di bandar kecil Guangdong. Dulu, ramai percaya belajar tidak berguna. Tapi kini, mereka sedar peluang mudah sudah tiada. Masa depan milik inovasi keras—kami perlu contoh dan proses pendidikan sosial."
