With all due respect to Sam Altman and everything he's accomplished, this is a pretty snarky comment that does not spend the time to thoughtfully answer the very real concern that OP presented. It's a huge risk to leave academia to participate in the possibly career-destroying alternative that currently exists. Academia isn't perfect with respect to career opportunities, but it does produce results.
There are many industries out there for which failure is hard - one of them is being an athlete in pro sports. If you aren't at the top, you won't make it to the pros. Not to say that a system that allows for failure is bad or good, but that I think it requires more thought than a simple response.
I think that people who signed up for YCR are looking for alternatives, and who will themselves be part of a biased group. In other words, it might be people who have struggled to find tenure-track positions in academia.
I think I'm mainly echoing the opinion that it's a little quick to say Academia is "fucked up", since with all it's flaws, there are still great virtues, and a more thoughtful response would probably be more appreciated. I also see the tendency for people to quickly judge academia when they haven't been in academia.
Nobody is quicker to criticise academia than academics. Mind you, nobody is quicker to defend academia when criticised by outsiders than academics too.
Academia has misplaced incentives here and there and can certainly be unfair at times, but I've never actually run into any large system which didn't have those properties.
Still, let's not exaggerate how screwed the incentives are. Ultimately the best way to succeed in academic science is to do good work. (Also, do a lot of it, and be good at writing about how good your work is and why it should be given lots of money.)
The point is: YCR may be as unforgiving if not more. As things stand, I think YCR will attract people who are either reckless or have nothing to lose. Not sure if I would want to target that audience.
Leaving academia forever isn't career-destroying. It's closer to career making. There are so many more opportunities in industry. Nearly any CS academic, if they simply quit academia immediately and vowed never to return, that act alone would make their career more promising.
I definitely agree that leaving academia opens new doors that can make you just as happy, but I can also say that there is not a place outside academia that is like academia.
