What I am seeing from studies is pretty troubling e.g. https://hachyderm.io/@shafik/113391494588227091
Folks feel more productive but actual objective measures say otherwise.
It is never about lines of code produced that is a silly measure by itself.
It is really about how many errors make it into production. If using AI code generators means a lot more bad code makes into production you are making a very poor tradeoff.
