Inheritance is isn’t always a terrible choice. But it is a terrible choice often enough that we need to warn the next generation.
But also, when it is not a terrible choice for a problem it is often not the best choice or at the very least equally good as other options that work in vastly more cases.
That’s a take I can agree with. My experience is that composition solves much of what inheritance is intended to solve and ends up being a more maintainable solution a majority of the time.
If we’re looking at it from a Rust angle anyway, I think there’s a second reason that OOP often becomes messy, but less so in Rust: Unlimited interior mutability. Rust’s borrow checker may be annoying at times, but it forces you to think about ownership and prevents you from stuffing statefulness where it shouldn’t be.

To be fair, that’s an issue in almost every imperative language and even some functional languages. Rust, C, and C++ are the only imperative languages I know of that make a serious effort to restrict mutability.
Thanks. I hate it.
I’m going to spend this thread agreeing with Rust fans, and I hate that the most. (I love you all, really, but you’re fun to try to wind up.)
OOP sucks because Inheritance sucks. This person’s brief non-shitty experience doesn’t change that.
Languages built around OOP suck where they use inheritance instead of interfaces.

ultra rare I’ve successfully inherited a concrete class, rarely an abstract one and 99% just impl an interface.

That does sound pretty cool.

How do C and C++ try to restrict mutability?
