Smartest people? Their tech stack is a dated cargo-culting of Google, hell, their newest thing is just using kubernetes with a thin wrapper. Their AI platform is a also ran in pretty much every aspect. Where exactly are the smart people?
1. Judging how smart the people there are by their tech stack is like judging how much horsepower a car has based on how many miles it has. 2. Even humoring that assumption, you’re conveniently forgetting React, Hive (+Hbase, hipal), presto, rocksdb, Cassandra, graphql, oauth 2, open compute, phabricator, hhvm, buck, and that’s just the open source stuff.
PHP could have died, but no, it got a new lease on life.
Hive is a bad copy of a google tech. Buck is a bad copy of a google tech. Hbase is a bad copy of a google tech. Rocks is cute, but it's a bit sad that it's at the center of literally everything in the company.
Phabricator isn't bad, but it's a pretty close copy to things at google.
And I think Google only joined the open compute initiative to try and talk facebook out of it's weird ideas.
