Nonsense. Network service layer separation solves a different problem than OOP. It doesn't replace it. Services and containers bring features and capabilities that OOP doesn't provide. It's orthogonal.

But I think that's really the point: it gets applied to problems it was clearly not meant to solve. The article doesn't really get into that, but that's how I'm reading it because I've seen it happen. To some programmers, every component of a program is its own service, even when there's no need to have multiple processes. The only tool they have is that hammer, so everything has to be a nail.
