These were titans that saw an entire industry as it could be as opposed to the "entrepreneurs" we see now that stand on the shoulders of giants and still manage to only reach their navels.
Do you really believe that, or are you just being melancholic? Every age has their visionary genuis enterpreneurs en the small-scale incremental-evolution enterpreneurs. The "enterpreneurs we see now" include people like Jason Fried, Elon Musk and Daniel Ek. Yeah, and founders of the get-a-notification-when-someone-unfollows-me-on-Twitter-app businesses, but people like that were around in the eighties too - you just haven't heard of them.
And, really, there's nothing wrong with either.
