That assumes you can write automated tests that reliably identify the mistakes over an entire codebase. Nice idea in theory. If it were actually possible, we would long since have generalized libraries of tests to catch every significant security and performance gotcha. What we have are static code analysis tools, fuzzers, etc. None of which have come close to eliminating security and performance problems. I don't see how AI somehome changes that.

Ah, I see what you mean now. Yes, my mind went straight to static analysis and testing (unit, feature, uat, mutation). Thanks for expanding on your point!
