AI can lift the weight, but you have to sweat the code to strengthen your mental muscles.
Don't skip your lines in the code gym.

We built a browser with GPT-5.2 in Cursor. It ran uninterrupted for one week.
It's 3M+ lines of code across thousands of files. The rendering engine is from-scratch in Rust with HTML parsing, CSS cascade, layout, text shaping, paint, and a custom JS VM.
It *kind of* works! It still has issues and is of course very far from Webkit/Chromium parity, but we were astonished that simple websites render quickly and largely correctly.

GPT-5.2 Codex is now available in Cursor! We believe it's the frontier model for long-running tasks.

I wouldn't have guessed that reading a blog post from @AnthropicAI would lead me to the Onion Futures Act of 1958
"In 1955, two onion traders cornered the onion futures market on the Chicago Mercantile Exchange."

Sqlite has 155,800 lines of C code. It also has 92M lines of testing code.
For each line of code, there's 590 lines of testing code.
Just massive.

With this very intriguing concept of Nested Learning (NL) by @behrouz_ali et al, we have continual indoctrination for AI.
Critical learning, where 2+2=3 is rejected on principle and 2+2=4 is not unlearned - that still remains a research challenge.

Potential @elonmusk robotaxis future:
1. Cheaper trips than ownership
2. Private car demand shifts to premium reliable robotaxis
3. Smaller fleets, higher utilization -> more traffic
4. Lose parking, gain road lanes

In a Cloudflare Workers vs Vercel benchmark, Cloudflare was slower.
Cloudflare engineers acknowledge the issue, solve it, and end up speeding up Vercel itself.

The speed of the cloud sometimes is amazing:
After you create an Amazon S3 bucket, it can take up to 24 hours before the bucket name propagates across all AWS Regions.
