Thanks. The "only 3 innovations have lasted over 100 years" premise isn't original. I first heard it at a graduation ceremony and it made a lasting impact on me. Ofcourse the speaker was very charismatic & way more dramatic than I am :)

But the phrase keeps popping up in several places. For instance, in Hedgehogging, Barton Biggs goes to a pre-2000 tech conference where they famously declare that technology innovations will propel the Dow to 20,000 in 1 year! Biggs calls bullshit & points out that genuine innovation like Air Conditioning & steam engines are once-in-a-lifetime event. He is asked if the internet is a "fundamental" innovation & he disagrees. He becomes a laughing stock. The next year the Dow drops 2000 points.
