I suspect that within a generation or two hand tools will be all that is used, as fuel becomes way too expensive and difficult to get.
Well, if you count a generation as 20-25 years, I would disagree. Two generations from now, I would tend to agree, if we make it that long. In the US anyway they will start pumping out natgas powered vehicles in big numbers sometime soon I bet.
heck, we are always one nut job fearless leader/president/head schmoo bad decision away from bad news anyway. So...could be, don't know. Geopolitics, big solar storm, you can never say never. made it through some previous ultimate doom periods in history, but...you never know either.
It's good to have the skills and tools to go either way really, it just pays to prep. I am setup, fuel is here, can use it, if fuel poofs, we can muster on one way or the other.
It is a good reason, one of several, to get many years ahead on the stacks now though.
I remember the big OPEC squeeze, ten bucks a gallon, two gallons maximum gas. That was politics, but it didn't matter, it still happened. Instant no job for me, no way to get to work. Bought the last two bicycles they had at the closest pawn shop.
