This guy has been pitching this message for years. He claims that by 2030 all energy produced on earth will be from solar power and all cars will be electric. As a point of reference, in the past 30 years that solar energy has been in use, we have just reached the 1% of total production.
The digital camera was invented in 1975. 20 years later the number of digital cameras sold was completely insignificant. Anyone projecting out the growth of digital camera sales would have come to the conclusion it would take thousands of years for them to catch on.
Then they hit a tipping point of "good enough" and within 6 years film cameras were completely replaced by digital.
The point is when the tipping point arrives, change is extremely rapid. The tipping point for solar and electric vehicles is about 2-5 years away (when it no longer makes sense to get anything else for most use cases).
Of course this guy's assumptions are unrealistically optimistic, but it will surprise everyone at the pace it moves, just like any technological disruption
