Does this solve the right problem? Getting some code on the page has rarely been the expensive part of building something. Indeed, some long-ago experience with code generators suggests that making it easy to create code makes many problems worse down the line.
I agree, I feel like it might be useful for whichever programmers regularly have to search Stackoverflow and then copy paste code snippets.
Then I feel like useful code produced by this tool will have to be treated in the exact same way as a rigorous code review: going through every part of the logic and ensuring it is correct. This seems like just as much or even more work than writing it yourself (if it is written in an unfamiliar way, you might need more time to wrap your head around it).
It's solving 'mechanical' problem. The optimistic twist on this helper is that it just raises the bar - human programmer should better be more useful than 'brainless' code generator - meaning not only being able to write a loop or solve leetcode task, but also understand context and what he's trying to solve for.
As you say typing code is not a bottleneck for problem solving
