Right, I’m pretty mundane actually, I don’t think I’m all that special and there’s lots of people at Google I’m envious of able to solve problems I can’t begin to crack. Some of the people working on build systems at google are using some dizzying graph algorithms for example.

Consider how Bazel must build and test the world’s largest(?) monorepo at scale incrementally on every commit.

Perhaps this is an artifact of Google’s size, but a lot problems turn out to be “well, this would be simple if our input was a million items, Unfortunately it’s a trillion items” and now all of a sudden asymptotic complexity matters.
