Some stuff is beyond many people to understand.

Some people have computer problems.

I could talk some about computers and the Internet, but I won't, because I know from past experience that it would be just another big waste of time.

If people wanted to know about computers and the Internet they would find out all by themselves.

That they don't know is because they don't want to, the info is there free on the Internet for anybody to find and see.

If people can't understand what they read about, then they also would not understand what I write about.
