Well yeah. I know he has been right on a couple of occasions. Still, how does this make me unwise for laughing at him? What went worse because I did so?

To be fair, his position was interesting in the 1980s. But he’s been hopelessly out of touch with the vast majority of computer users since the 1990s. He can keep harping on about the GPL and keep watching the world pass by.

Seems weird to laugh at someone who pretty consistently predicts the future. Does it make sense to laugh at physicists too? Was their predictive theory only relevant in the early 1900s?
