Back in 1995, when Robert Loest and I were telling the world about our new mutual fund IPS Millennium, we told a story explaining that, historically, change within a civilization first occurs at an inflection point and is followed by big change and then a long plateau period.
We shared how civilization started with hunter-gathers, and people maintained that lifestyle for over 100,000 years. Then, we had an inflection point, learning to plant seeds and grow food. This was the Agricultural Revolution of the Neolithic Era, and it went on for a few thousand years.
