It can happen to you.
Dramatic failure, maybe not: but there are plenty of startups out there in that gray zone of "we don't really know what we're doing but we have several redeeming qualities!"
That zone, the upper 10% of "hyped" startups shall we say, are far more deceptive, and therefore dangerous, than the "obvious" bad companies, the bottom 90%. It's easy to laugh at all those investors who got hornswoggled by an out-and-out narcissist. It's less easy when the team is super- smart, the founders super-motivated and the only factors missing just happen to be what separates the 10% from the 1% who are truly successful. It could be product-market fit, work-life balance, or whatever the team needs at the moment. The only way to know is to be super-paranoid[1]
Much like the stuff on /r/subredditdrama or /r/cringe, spectacles of human foibles convey "I'm better than the worst, so I am good." which, for me, translates into a false sense of confidence.
