I don't think the companies today are any less impactful than the companies of yesteryear. What's different is that now, because of consumer Internet, "cool people" are getting into computer programming. The old guard of Silicon Valley was very awkward and nerdy -- Bill Gates is the archetype. Today's software entrepreneurs are more like Jack Dorsey -- they dress well, have no trouble getting dates, and people on the street know their companies. The nerds look at these people and say "This is OUR thing. Get out of here." And resent these new unwanted arrivals.
