Still in the peak of inflated expectations, I see. Give it 2-3 more years to get to the trough of disillusionment.
More companies than people realize are already building and scaling with DO SQLite or Turso internally. Almost every company I've talked to that chooses Postgres hits scaling issues around Series A — these companies aren’t.
"SQLite but distributed" is like NoSQL during its hype cycle: a good choice for one or two use cases, a bad choice for most every other use case, yet people are choosing it for every use case, because it's trendy and has lots of marketing hype. It appears to work at first, so people rejoice and make bold claims about it solving every problem in the universe. It's only later that the poor design choice bites them in the butt and they go looking for the next trendy thing.
