Idea for essay?

I’m in the IB program and they require us to write a hugeass essay on a topic of our choice. I was thinking of an essay on an aspect of programming (or computer in general, or something like that…) since almost no one at our school programs (I feel kinda lonely, lol) so I might get extra points for originality or something.
This is a project that will take almost a year.
So does anyone have suggestions on what I should be writing on?

Thanks =D
