It's funny. I started my career in tech as a software tester, where I wrote tests for devs writing code. Now, a quarter of a century later, as I write unit tests and agent evals, my career will likely end as I write tests for... LLMs We all testers now! Suckit devs!?!

Can Claude Sonnet 4 write x86 assembly? I ran an experiment today and got Claude plus Claude Code to build, run and debug a pleasing Mandelbrot fractal in assembly, compiled via Docker on my Mac Full details, including prompts and Claude Code transcript, here: simonwillison.net/2025/Jul/2/m...
Terminal window showing code diff for Mandelbrot fractal program. • Now I need to fix the Mandelbrot iteration logic as well. The current fixed-point arithmetic has issues: • Read(program.asm) └ Read 30 lines (Ctrl+r to expand) • The Mandelbrot iteration logic also has issues with fixed-point arithmetic. Let me fix this too: • Update(program.asm) └ Updated program.asm with 18 additions and 12 removals showing assembly code diff with line numbers 63-91, including removed lines marked in red for fixed point multiplication calculations and added lines in green with 64-bit arithmetic conversions, comments describing z_real and z_imag calculations, and mandel_done logic checks.
A pleasing ASCII art Mandelbrot set, zoomed to the expected level, white text on a black terminal background.

If your tech optimism doesn’t make room for existential dread, you’re not paying attention. But if your pessimism doesn’t make room for existential astonishment, you’re missing the plot. We are apes with code. That can be terrifying. It can be transcendent. It’s OK if it’s both.

The Golden State Warriors have been up in arms over how the Houston Rockets have treated
Stephen Curry in their first-round playoff series.
The Rockets have been extremely physical, with Dillon Brooks even targeting Curry's injured thumb.
Despite the uproar over that, Brooks had a message for Curry and the Warriors before Game
6.
"If he doesn't want contact, he should play tennis,"
Brooks said.
