It's always been complex, and getting more complex, it is likely that you are just becoming aware of the complexity, when you thought it was simple. There's also the phenomenon of companies using tools/techniques that others are using without understanding why others are using them. I work for a company that needs k8s, kafka, and distributed systems. The previous company I worked for did not need that, at all, and so they didn't. The company before that didn't need them either, but thought they did and tried to move their single, relatively simple ETL pipeline to k8s, and it was a disaster. But companies that need those tools, really, really need them. We don't use "nosql" (hate that term, it is a really dumb term anymore, sql use or not is completely orthogonal to the problem, "non-relational" or "non-OLTP" is better) databases because we think they are cool tech, we use them because traditional, relational, OLTP databases don't work for our use cases. But if someone comes to me and asks what database they should use, I always say "postgres", unless they can present a compelling reason postgres won't work. The problems we face are tremendously complex, though, and only getting more complex. We fight back with tools, but there are years where the tools are failing to keep up.
