I once attended a university lecture on entrepreneurship. In it, the lecturer moaned that the pace of technological change has slowed and big things weren't happening anymore. It turned out he was an aeronautics person, and there was no concorde replacement, the 747 was 30 years old, no more moon rockets, etc. I didn't interject but I thought - how can you live in a world upended by the internet and say no big changes are going on? The answer is that it all depends on your focus.
