Whatever Postgres in WASM ends up being used for there's no way it repeats all those circumstances - at minimum Postgres is just a more appropriate tool then MongoDB circa 2015.
As in they will crash and burn?
There's only one way to architect a PaaS. Next.js and Vercel's offerings are, essentially, also the same.
The real risk is having one person build it all. They have a team but not really. Personally I believe that's a good risk to take.
But I think it will take a powerful psychological toll to operate this way, having to pretend to have a team (because investors like teams and not solo founders), having to pretend this isn't Meteor (because investors don't like being reminded of "losers"), etc. etc.
Like downvote random Internet comments all you want, but actually I think it's a great idea to have one person do "Better Meteor," it's not my fault investors don't.

In case you're talking specifically about supabase here, we're a full team: https://supabase.com/humans.txt
Member mini mongo?
Supabase will be Meteor in no time.
