Here you have it folks, seniors don't make mistakes.

When I'm confident something will work it almost always works, that is very different from these models.

Sure sometimes I do stuff I am not confident about to learn but then I don't say "here I solved the problem for you" without building confidence around the solution first.

Every competent senior engineer should be like this, if you aren't then you aren't competent. If you are confident in a solution then it should almost always work, else you are over confident and thus not competent. LLM are confident in solutions that are shit.
