## Just a general question about complex

No.14429924
I had no problems with complex numbers in high school. Just as I progress I think there is something, basic, yet fundamental I am missing.

We need to solve the hard problem of consciousness for all living beings as soon as possible. How exactly consciousness appears from matter and how it's influenced by it. This is more important than quantum physics or space.

I don't remember A NY THING i ever learned in school.
Maybe arithmetic and the basis of mathematics is what i still use today, and not even that. Geography is google for me and biology is irrelevant. My own language is the last thing i need in specifics, French is useless -i couldn't save myself for one moment in Paris without asking Parlez vous anglais?- German is essentially the same.
Economics.. zzzz who gives a fuck
and music is redundant. The Beatles didn't even know how to read notes.
English is all self-taught through movies and internet.
All schools should be banned and nuked.
I wonder what stuff like princeton or harvard in actual fact contributes to a student's life, except socializing and feeling elite.
