I agree, Bob is great. I think scaling a concept is also really really important. We need features but we need scalable frameworks and platforms to support these features. Bob's not going to write the distributed db system that makes his feature look good, but that also needs engineering. That too needs to be good enough to ship and no more btw, but it's more often the work of a team that has to slow down and think carefully about what it's doing, especially when evolving long-running platforms
