Why use a programming language at all? Why not write everything in machine code for that matter?

The point is that Haskell's position on the abstraction spectrum is no less arbitrary than that of Go or C++. You cannot divorce the relative advantages and disadvantages of various levels of abstraction from the realities of maintenance, development time, readability, complexity, and yes, the fact that not everyone is as big brained as you, because by not writing machine code, you have already acknowledged that these realities matter.

I can just as easily come up with my own programming 'language' where there's a 1-to-1 mapping between a countably infinite set of characters and every unique Turing machine. Want to write a program? Find the right character. This is the most terse, most elegant programming language ever, but clearly helps no-one.

The best abstraction is the one that is the most universally understood.
