Arseny Khakhalin @khakhalin.bsky.social · 28/09/2026llms brought engineering to the same place where knowledge was for some 100 years and language learning for at least ten. Same as one can always pick up a book, or open Duolingo, or start drawing, you can now build _anything_ in a few months. And that's when folks realize that they don't wanna. 250

The frontier in bio is much better defined than in math, the next steps are way more predictable. It's VERY common for 2-3 labs to discover the same thing independently!

Remember this classic intro to algorithms where you ask students to create a procedure for something simple, and then misinterpret it horribly, to show that now they have to be really precise, that computers work on precisely defined narrow logic rails 120

Arseny Khakhalin @khakhalin.bsky.social · 25/09/2026One wonderful thing about Opus 5.5 (and it may be the key to its helpfulness) is that if you ask it in a new project "Would you like to set up long-term memory for yourself?" it answers "YES!!
