Bazel 2.0
For anyone thinking about Bazel for their project/organization... run as fast as you can in the opposite direction. It's easily the most complex and unintuitive build systems in the world, and I'm saying that as someone who used SCons. At the last job where I used it, I was on a team of 5 whose responsibilities included Bazel upkeep, which required anywhere from 10 to 50% of our time. This was used by a broader engineering team of 50, working on 3-5 "big" projects and a few dozen small ones.
