I like your K-wave thinking. But I didn’t have #5 in the 1990s. By my reckoning #5 is the Age of Information and Telecommunications. It began in 1971 with the release of the first mini-computer, the PDP-8 from Digital Equipment Corp. #5 is just about spent. I see #6 starting now. The rise of industrial capacity renewables plus electric cars on the market tells me we’re on schedule. Watch for cheap sea water purification to alleviate drought. IT will be driven by renewable electricity.

That said, my big concern is that #6 could be stillborn or delayed while big oil drains the last of the oil from its reserves. That would be incredibly short sighted because about 30% of our petroleum goes into making things like synthetic rubber. IT takes 7 gallons of crude to make an average car tire, 5 for the rubber and 2 for driving the process.
