The first time I pasted a screenshot of a PR review thread, adding just "I had some review comments, fix them" - and it perfectly solved everything, made small commits, and pushed it upstream - this was such a shock.

I now try to keep pushing the boundaries and see where it stops understanding my intention. Give it impossible tasks, gigantic projects, complex architectures. Last result: I wrote a complete OS including MPI, TCP/IP, and a GUI from scratch in only a week, while investing just a few hours a day in it. It even runs Doom!. Coding as a profession is over, but there's such a difference between the result if you approach this with a professional mindset, that I think the software engineering discipline can still provide massive value.
