Yep. All of us tech folks read sites like hackernews and read all about what the latest hot Silicon Valley tech startup is doing. Or what Uber is doing. Or what google is doing. Or what Amazon is doing. And we want to be cool as well so we jump on that new technology. Whereas for the significant majority of applications out there, older less sexy technology on modern fast computers will almost certainly be good enough and probably easier to maintain.
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.
