Why is the UX of the human brain so user-hostile?

Using terms from technical/software fields to talk about brains and behavior leads to inapt analogies. People are not computers.

Brains evolved from the material available, to serve some basic purposes: improve chances of survival and reproduction. Brains were not designed and don’t have “UX.” What each of us experience is an emergent property, or side-effect, of the brain’s evolution.

The concept of rationality is a human invention (like morality). Neither are inherent properties of the brain, they are learned behaviors and social constructs.

Because up to this point on the evolutionary scale the brain UX hasn't been a sufficient enough deterrent to reproduction.

You're not owed a good experience, or a healthy brain, or a nice life. There isn't a manager to complain to. I'm sorry.

Would you define some of your words? I have never seen such combination of words as "UX of human brain".

So hard like what? If it is rational to change then you change, otherwise you don't. Have I just missed something?
