And it takes time for people to transition. Think about a major corporation. If they want to roll out a new piece of software, that is a three-year commitment, minimum, just to get people to spend most of their water cooler time talking about how much they hate the new software.

That is extra IT hours spent on training users over and over and over again on how to use the new software.

And after three years, somebody will step in and say, “Hey, why don’t we try software Y, It’s better than the software that we just rolled out”, which queues a new three-year software rollout cycle.

Extrapolate that out to 8 billion human beings, well over 2 billion of which drive vehicles or utilize personal transport systems that are internal combustion engine powered, and you’ll begin to get an idea of how difficult it is to transition everyone away from fossil fuels.

The good news is that it is happening, and barring major accidents, we will probably get most of the way there during our lifetimes.
