Just onboarding a skilled/experience new team member has been painful all around. There is so much you can get in a traditional in person whiteboarding session, or that one has developed the skills to teach in person. I think much of the issue comes from communication limitations or lack of skills in remote communication. That could be as simple as a senior member with 30 years of xpeirence teaching someone in person and can read body language to understand when to slow down or go over a topic again. Without that feedback source they lose a major component of their effective teaching style. Even checking work or notes can take 2-5x the time, swapping presenters or losing side by side comparison from two different views. Anecdotally, I've found it easy to get lost in what I'm presenting and forget to slow my sentences for clarity over an often poor call or connection and some of the people I work with are not even able to view meetings at home due to poor internet access.

To your point, I hope students today are learning how to learn/communicate/perform at home and building the skills required to do so in the field or these issues will be compounded after graduation. It's super easy to slip under the radar or just get by, in many cases it was like that before the pandemic. I think there will soon be lists of interview questions related to how one coped with the challenges of learning/working from home, what difficulties thy overcame, and how they did so as an individual/team/company. It's not like I'll be at a vendor conference to compare those notes with other people any time soon.

It's already near impossible for people not from top tech schools.

I don't know what generation you are, but for millenials, the 2008 crisis was a real doozy. Anecdotally, only maybe 20-30% of my cohort found stable, well paying full-time jobs in the 10-12 years since that recession.

Many of them put their life plans on hold due to not being able afford things that a family generally requires.

So the "future" is already here. And has been for about a decade.
