It *certainly* wasn't obvious in the mid-70's, when Intel had picked up its pieces and put together a microprocessor chip (the 8080A) which cost a significant fraction of what a new car cost at the time, that VLSI CPU's were going to be replacing boards full of TTL logic. It was Intel's competitors - notably Motorola and especially MOS Technology - who were responsible for driving microprocessor CPU costs to the hundred-dollar-level and below. That's when times really began a-changin'. Tim.
