But I left Google early this year to work at a startup. I can tell you that the confidence I have with Google's tooling, testing infra, presubmits etc. are miles ahead of the confidence I have with our current pre-commits. But at Google we had millions of daily-actives and at the startup we have dozens, so if something breaks it's not too bad.
Do any other company start as many new things as Google? Google builds things extremely quickly for being that large. Then they shut them down just as quickly, which is another matter, but it is hard to argue that they are slow at building products.
