Yup. However, at the time, the exponential growth in computer power had been pretty well established.
The cheap ram and long-term storage was predicted. The cheap CPU was predicted. They all fell along the same growth curve that had been going on for some time.
But a lot of the actual applications weren't so easy to predict, and that is what makes the future fun.
I expect to be, and I expect to be driving the same 1974 car that I am driving today. It should be up around a million miles on the odometer by then. But then, I'll probably still be using film and listening to CDs as well, so I am clearly an outlier.
