DevOps may be hyped, but it's not outright bullshit. DevOps is just the realization that you would rather have a fewer people knowing everything, than many people knowing disjoint areas. The same force underpins the full stack crowd, or the notion that pizza size teams are more efficient. While this is not always possible in practice, in my experience it is better if the project is small enough that you can pull it off.
The memory bandwidth in one single person's brain is simply much higher than the bandwidth between people. To maximize performance you want to run your project on as few brains as possible.
