It's not about "being able" it is about being efficient. There are many cases where current AI can provide boilerplate and good examples for doing something specific, which eases things a lot.
There is a lot, of course, one can't take 1:1 into the final product, but it helps to find the right libraries, helps to find patterns, the right parts/functions to use where verification in the applicable documentation or source is a lot simpler than finding it in the docs to begin with.
Using it as a tool, while not a source of truth can be good.
And don't get me started about writing all the boilerplate which sometimes is needed, which is too complex for a simple editor shortcut, but too tedious for me as a human. That I review and fix a lot faster than create by hand.
