> I find it hard to believe deep down there are generally curious tinkerers who haven't found their way to a programming language of some sort? I know one. He's rigourously logical. As a hobbyist, he's worked with electronics and complex mechanical systems: analogue cameras and vintage hifi were two of his passions. He's used computers for decades, but for some reason, they never clicked with him in any deep way. I've explained Turing machines to him, and he understands the concept, but it didn't trigger an interest in going deeper. Fundamentally it's about fear, I think. Fear of facing one's own intellectual shortcomings. Computers expose that in a more raw way than tinkering with physical objects, I think.
