At the end of the day, there are a bunch of different things going on. Higher interest rates, general overhiring during COVID for whatever reasons, and (yes) AI. And probably more macro trends. Maybe at some point we'll see some data-driven analyses but, from what I've seen, it's really hard to tease all the threads apart.

Remote work would seem to have a potential impact on mentoring and future development but that seems like a longer term trend. But, maybe, as the article suggests, some companies that are heavily remote are thinking that entry employees are going to be harder to develop--but that's a problem for the future so better not hire them today.
