2. I believe you completely misread the parent's point: that there are only a few technologies that are 100 years old. (Not sure what that means with regards to the 'transformative' argument, but still...)
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.
