I have run into folks that don't understand polymorphism. It seems that it is not even being taught.

One thing that geeks love doing, is telling other geeks they are bad at what they do. It gets a bit grating, but I’ve come to the realization that I need be true to myself, because it’s a losing proposition, hanging my self-respect on the opinions of others.
I do what I do, and get the results I get. I don’t spend much time, worrying about how I compare to others.

That should make you even better equipped to design simple interfaces that require as little depth of understanding as possible from the next person.
Similarly I've happily spent my couple of years with functional purity and higher-level types in academic languages - function signatures sometimes orders of magnitude longer than the implementation itself - yet I dip into those depths only as necessary and try to keep my TypeScript interfaces as "stupid" as I can get away with without compromising on semantics. Enums are too fancy for me. I try to keep state at minimum but there's a 'let' every few thousand lines or so.
And all that venturing into lower-level concurrent C++, agent systems, parallel programming, erlang? You ain't gonna know about any of that looking at my concurrent Rust.

Oh, well, what I'm writing above is from the point of code meant for collaboration - either open source or professionally. If you're coding for yourself only, or in academia, by all means stop trying to please the crowd and start cranking out some poetry!
I write code that I want to see in a year.

Is it? I’d agree that there’s increasing awareness of the limitations of OOP, and I’d agree that using inheritance excessively can be one of the limiting factors, but I don’t think I’ve ever personally seen anyone criticised or penalised for using inheritance appropriately.
