Which AI? LLMs are coding facilitators and code producers.
A problem is solved when the solution is reliable. Non-deterministic Neural Networks are not reliable. In fact,

that suggests an expectation of process and procedure, which is still not a capability of current architectures.
Sure, you can ask a brains-deficient operator to perform a huge task, but then you'll have to check the whole product, and that remains not cheap.
The tool itself (AI) may not be reliable, but that is also very true for every other tool (e.g. Human). Also, you are right about when a problem is solved, but this doesn't need the tool to be reliable as you said, just the solution part. Hence, as long as the produced code works as intended, it doesn't matter what you used to produce the output.
