Reading and studying yourself isn't the same as having a qualified person teach you.
He's in his 70's, it shouldn't be surprising that he doesn't know how to work a computer.
He obviously doesn't do it to get a job or he'd be done decades ago. He does it because he wants to learn. I like classes that have little to no job application but teach me a lot about the world. You guys should star in an Everest College commercial .
I just isnt rational to me. I mean, if he had a career, even as an underpaid teacher, and did this, it would make sense. But he works as a parking attendant to pay for school. He's qualified to get a better job, and has been for probably 25 years.
He could start his own business, become a professor, or anything in the world. He has at least one doctorate. He opened up doors of opportunity and wont walk through them.
