I see a lot of comments here pointing out that uncertainty is the most demanding parameter when doing a postdoc. Well, I'm not in a position to comment on that, because despite being a few decades old, I haven't really started my acamedic career yet - allthough I'm inching my way into it, should nothing notably better come up. Mind you, this is Germany, where there's no tuition to pay and they accept you at university if you've got the grades and the track record to prove you really mean it.
However, there is one thing that I've been noticing ever since the last decade started with the first internet bubble:
Today uncertainty is everywhere, no matter what you do.
It's a simple fact, and I'm sure most of you would agree, that we are moving head on into a cyberpunk world the likes described in William Gibson and Neal Stephenson novels. Move to post-scarcity economy, peak capitalism, permantent environmental damage, constant economic and currency votality, work & travel throughout your career, constant precarious personal life, etc. It's happening all around. Regular lives of people falling apart left, right and center and those stuggling to maintain a modestly secure life feeling more and more miserable by the day in doing so, because they have to cut so many throats and compromise in to many places to even be able to. I've had 3 jobs this year, the current one with a web programming hovel with no versioning or deployment, a passive-agressive boss, 5 different main admins in 5 years and a higher turnover rate of programmers than McD's has with burger-flippers, accompanied by the according codebase. The last gig was 60+ hrs of unpaid overtime in 7 weeks, working on a project that consilidates Germanys online travel booking market by orders of magnitude and will put quite a few people out of work when the rush is over.
I'm certain we're moving into a world where acamedic rank will count less and less and even universities will be consolidated, because their cruel selection mechanisms don't guarantee a solid career anymore. And do we need them? I can get more education off Khan Academy today than I could of half of the universities in Germany 3 decades ago. For free, without moving anywhere. Those are the upsides of a cyberpunk society.
My 2 cents.
