I'm not sold on the evidence of much in the way of programming language features from the "object oriented" era.

They were pushed by cultish types with little evidence. There was this assertion that all these things were wonderful and would reduce effort and therefore they must be good and we all must use them. We got object oriented everything including object oriented CPUs, object oriented relational databases, object oriented "xtUML". If you weren't object oriented you were a pile of garbage in those days.

For all that, I don't know if there was ever any good evidence at all that any of it worked. It was like the entire industry all fell for snakeoil salesmen and are collectively too embarrassed about it to have much introspection or talk about it. Not that it was the last time the industry has fallen for snakeoil...

If encapsulation wasn't useful, we wouldn't write microservices.

If abstraction wasn't useful, we wouldn't use containers.

That's not evidence though even if we take it as true. You can of course make layers of abstraction or encapsulation without "object oriented" languages.
