You're right. I think the point we need to discuss here is, to be clear, dividing the contexts in which defensive programming is strong and where it should be aggressive.

I think the overhead of implementation is enormous, but I believe AI can write it. However, before even reaching the 'implementation' stage, that is, at the planning stage, sufficient data must be collected for the implementation to be safe.

In that respect, I think Jane Street already has enough data and modeling capabilities. However, I think it's a bit difficult to say whether this approach will take shape in many other domains.

In that sense, I also think that the reason many industries are doing this kind of fast deployment and experimental tooling might be a preparatory step for that kind of modeling. Have a good day Thanks for the good comment. It helped me think more sharply as well
