Big brain tech dude got yet another clueless take over at HackerNews etc? Here's the place to vent. Orange site, VC foolishness, all welcome.
This is not debate club. Unless it’s amusing debate.

UUIDs make great primary keys in some applications. If you generated 100 trillion UUID4s, there’s about a 1 in a billion chance of finding a duplicate. Thats usually good enough for my databases.
The issue here was that they used a single UUID instead of generating a new one for each record.
they also stored this thing as a fucking string. looking up strings is costly.
This sounds like a case of premature optimization to me. We have plenty of databases using strings as Ids and they're all more than fast enough for any of our purposes. And that's with considerable volume going through.
I've never seen bad performance from string ids be an issue.
so we're calling "not doing pointless unnecessary work" premature optimization now? cool cool
Making me learn how to do things the right way is premature optimization
ok shut up now
