I accept the fact that not many people will read my thesis.

Scientists in the field will not read it because they are not interested in all of the details of the analysis. They are only interested in the result, which will be published in a four page paper that only broadly explains the methods of the analysis.

My mother will not read it because I won't be writing it for her. When she asks me what I did, I will explain it in a way that she can understand. If I'm lucky, some science journalist will write an article about it, and I can send her the link.
