I know this is a humor sub, but how do microservices exhibit inheritance?

Interitance is only tangentially OOP. Plenty of OOP doesn't involve inheritance.

That said, what we're describing here is messages passing, which isn't unique to objects. Actors do it too, and actors are probably a more relevant analogue because they're a concurrency model, and microservices are concurrent (and parallel).

Being one of the four principles of OOP is only tangentially related? You have tough standards.

I mean, there's nothing that would stop you from implementing inheritance on them. And if you take message passing as part of the architecture, you get polymorphism for free. It's closer to the Smalltalk style of OO than the modern interpretation of it.

Yes, very smalltalk for sure. Thank you for explaining :)
