Then you have in all those decades for sure never seen a GUI program
done with the Win32 API (not OO, ugly, hard to grasp) and a Delphi
equivalent (OO, elegant, easy).

This is your opinion, not a fact as your wording suggests. If the OP
is asking for examples it doesn't make sense to answer "Hey, I don't
know any examples".

I don't think so. OO is modeled after human reasoning. Look e.g.
at phrases like Bob calls a friend, Bob learns math.
What is better:
Bob.call(friend) or human_call(Bob, friend), Bob.learn(math) or
On the other hand there are cases where the emphasis is on the
verb, e.g. compute the sine of alpha: sin(alpha) is perfect,
no need to code alpha.sin(). Therefore I like hybrid languages
like python giving the programmer the freedom to choose an

Excuse me, but to present your personal experience as a law of
nature is not very helpful for a newbie seeking for advice not
for propaganda. It is plain wrong to claim that procedural
programming is kind of natural and OOP is rocket science.

There are terrible OO libraries out there but this is not
a genuine feature of OOP. Bad code can be written in lots

It's not a question of taste it's a question of the kind
of problem to solve.
