Yeah, this guy isn't merely uneducated, he's got a screw loose. Bipolar Disorder strikes the educated and uneducated alike and sometimes you find very dumb, uneducated bipolar people who, none-the-less have the manic confidence and drive to talk your ear off. (Think: Charles Manson.) On the other hand, he may simply have been on methamphetamines.It seems that what originally motivated him to ban computers in the home was the internet.
In his words, "if they need to know something, they can go to the library and look it up in a book".
He wants to turn back the clock. He thinks that we should start eliminating the technology in our lives.
Someone asked for specifics. I don't want to regurgitate everything that he said [nor could I], but as an example, he accepts that global warming is real, but it seems that we don't have to worry about the effects for 500,000 years. I have no idea where the magic 500K number comes from.
There was a strange guy who used to hang out at the cafe who talked everyone's ear off about everything and also made delusional claims such as having worked secretly for Nasa and having been sent into space, and then came the intimations that he was the reincarnation of Jesus. He started getting skinny and sickly. Eventually he was diagnosed with leukemia. Now, after a few months of treatment, he is suddenly sane, not nearly as opinionated, and looks physically healthy. Your tire guy might well have an undiagnosed physical problem.
