Just write your code, so that you (almost) don’t need comments (i.e. simple to read). The problems with (most) comments won’t be solved by AI.
(in-code) comments only make sense for me in roughly these scenarios:
complex piece of math possibly from a paper (e.g. a ref to the paper where it is explained)
function doc, here AI may really help at some time (right now, I’ll rather write it myself, AI represents this post very well in an even more verbose and literate way than the typical junior dev…)
