Neither of my parents (both college-educated with multiple graduate degrees) ever really "got" GUIs or the web. They learned computing with punch cards and later with teletypes and vt100 terminals. They were fine with DOS when PCs came on the scene, but just never really made the leap to graphical interfaces and the web. My dad in particular thought it was all a bunch of silliness and it actually contributed to his loss of interest in computing (he used to program Z80s in assembly to control laboratory equipment. He could also progam TI 980 minicomputers by toggling machine code in on the front panel. But he never saw the point of the web.
