This is a great point, previously the tradeoff was build in python in 2 weeks versus 2 months and even if your app performance is worse you built it faster and maintain it more easily. Now I am wondering, for all the devs who do not have experience in Rust, can they still maintain the code when the usage limits get hit? Since there is an automated test suite and easily verifiable results, this is a good area where you can be assured the compiler is working properly; however, if new features need to be added, I'm not sure how easy it will be for them.
Honestly it is a moot point. The benefit of languages like Python compare to Rust still hold. Algorithmic complexity rules the roost. For the hot path, write a C extension that is rigorously tested. Python you can iterate much faster same as any scripting language.
The AI can iterate faster in Python too, guaranteed, because you don’t have any compile time.
Also, this is how AIs already get stuff done: they write SCRIPTS to perform tasks in a sandbox with tool calls. This is the future, dynamic languages, not using static languages.
