I've had several experiences where I attended a tech talk by someone from Uber, and never once did I come away with the impression that the problem they were trying to solve was the kind of thing Fred Brooks had in mind when he coined the term "essential complexity."

That said, volume and velocity aren't the only kinds of scale that technical teams have to grapple with. I've spent enough time at a big organization to understand that Conway's Law costs CPU cycles. Lots of them.

They struggle with the size of their mobile apps so they've got that going for them
