The coding tools are not hard to pick up. Agent chat and autocomplete in IDE's are braindead simple, and even TUI's like Claude are extremely easy to pickup (I think it took me a day?) And despite what the vibers like to pretend, learning to prompt them isn't that hard either. Or, let me clarify, if you know how to code, and you know how you want something coded, prompting them isn't that hard. I can't imagine it'll take that long for an impact to be seen, if there is a major impact to be seen.

I think it's more likely that people "feel" more productive, and/or we're measuring bad things (lines of code is an awful way to measure productivity -- especially considering that these agents duplicate code all the time so bloat is a given unless you actively work to recombine things and create new abstractions)
