The same effects have also made long postdocs less common, and it's even possible to jump directly to a tenure-track faculty job from a PhD with no postdoc in between. Alternately, people seem to be doing a kind of "industry postdoc". You get an industry job, but one that lets you publish (DeepMind, Facebook Research, some startups, etc.), and after a year or two you either find you like it and stay, or you use that as a springboard to apply for faculty jobs, treating it as having been basically a high-paid postdoc.
Still plenty of stuff to complain about, but the job market looks far different than in the natural sciences or humanities.
