I think we actually do believe it, do you believe Fable 5+GPT-5.5(+ the whole model zoo) in loop with adversarial (no budget limit) or a 10-year experienced SWE?

We are talking about "codebases" but realistically we won't even be checking the filetree of them soon, it will be all blind, containerized and verified with pseudo guarantees which are good enough to build serious things. We don't even write documentation for humans anymore, we need to look at the trends and the reality within companies, most developers became "callcenter agents" in a matter of only 2 years and literally most of them are not even using proper automated tooling yet as we can see the "vibe coding" trend with Claude Code which is weak, by far most work done daily by developers is already automatable entirely, but with exceptions, sure, but in a few years those exceptions will become rare.

There will be niche problems about legacy products, sure, but legacy products will all be replaced over time, if we think in depth, why do we even need that many languages, that many tools? Tomorrow AI will write 99% if not all code existing ("code" doesn't even matter anyway), so it's much better if it's specific to AI and not playing this dance where we think we are doing a meaningful human contribution on an "AI-made codebase".

For context, I have 2 decades of software dev behind me.
