“If nobody doubts your direction, you are already too late”

This means, when nobody doubts your direction everybody already knows that the direction you’re going is the right direction

Most beautiful code I have seen shared in public recently.

Built by Andrej Karpathy - single file of 200 lines of pure Python with no dependencies that trains and inferences a GPT. This is how it should be taught to everyone trying to get into learning LLMs.

This might be the cleanest, most elegant public code drop in AI this year.
Karpathy's new "art project": microgpt (https://t.co/itMLfmOu5l)

→ Single Python file (~200 lines)
→ No PyTorch, no NumPy, no external libraries at all
→ Full working GPT: data loading → character tokenizer → tiny autograd engine → GPT-2-style transformer → Adam optimizer → training loop → inference/sampling

It's the bare-metal essence of what makes large language models tick - everything else (CUDA kernels, distributed training, mixed precision, flash attention, massive datasets…) is optimization & engineering around this core.

Perfect starting point for anyone trying to truly understand LLMs instead of just calling APIs.

Highly recommend reading + running it. Changes how you see "AI is just matrix multiplies + softmax" from abstract → concrete.

MIT student Arnav Kapur built an AI headset that reads your brain and pulls out your thoughts...🤯

It is called AlterEgo...

No speaking it just turns your thoughts into words....

🧠 MIT recently completed the first brain-scan study on ChatGPT users—and the results are deeply revealing.
Rather than boosting brain function, prolonged AI use may be dulling it.
Over four months of cognitive data suggest we might be measuring productivity all wrong ⤵️

In MIT’s study, participants had their brains scanned while using ChatGPT.
→ 83.3% of users couldn’t recall a single sentence they’d written just minutes earlier.
→ In contrast, those writing without AI had no trouble remembering.

Brain connectivity dropped sharply—from 79 to 42 points.
→ That’s a 47% drop in neural engagement.
→ The lowest cognitive performance among all user groups.

Even after stopping ChatGPT use in later sessions, these users showed continued under-engagement.
→ Their performance remained lower than those who never used AI.
→ This suggests more than dependency—it’s cognitive weakening.

Beyond the scans, educators flagged the writing itself.
→ Essays were technically solid, but often called “robotic,” “soulless,” and “lacking depth.”

Here’s the paradox:
→ ChatGPT makes you 60% faster at completing tasks…
→ But it reduces the mental effort required for learning by 32%.

The top-performing group?
→ Those who began without AI and added it later.
→ They retained the best memory, brain activity, and overall scores.

Using ChatGPT can feel empowering—but it may quietly offload your thinking.
→ You gain speed, but lose engagement.
→ You get answers, but stop learning how to think.

The takeaway isn’t to avoid AI—but to use it intentionally.
→ Use it to assist, not replace your mind.
→ Build cognitive strength—not dependency.

MIT’s early study on AI and the brain lays out the stakes. The way we use these tools matters more than ever.

Japan 🇯🇵 understands technical development and they have been doing it right over the past 25 years.

I want to say the USA 🇺🇸 will but the reality is that 🇯🇵 will likely be the first non CONMEBOL/UEFA nation to win the World Cup over the next 20-24 years

Google just dropped a new LLM!

You can run it locally on just 0.5 GB RAM.

Let's fine-tune this on our own data (100% locally):

Japan football game is definitely in a whole different level, the intensity is so high, as a midfielder they never allow me to turn where I could do it easily back in my hometown 😔

This is mostly one-shotted using Cursor. A simple multiplayer game using Three JS and Socket IO.

The idea is to build an oversimplified Monster Hunter type of game but for browser, where you could login, beat the boss with friends/random folks, and go to sleep.
