well I think a lot of problems arise in these fast running companies. a company that scale's up slowly and brings their tech stack up and forward with a small team that slowly adds people (so that everybody can learn from people working a little bit longer on the stack) will lead to a way more sane teck stack than a extremly fast growing team + technology. also I loved some talks about instagram. (https://de.slideshare.net/iammutex/scaling-instagram https://de.slideshare.net/iammutex/scaling-instagram) Scaling: replacing all components of a car while driving it at 100mph (And the end slides 150+ are awesome, too). And while they use PostgreSQL and talk about everything, they also did engineering quite right and prolly that's the problem of Uber. They tried to get to big to fast and know everything burns (not just their tech).
