> I just think we could have transitioned away at the turn of the previous century... and saved ourselves a lot of pain. I mean, that's a hugely provocative statement that needs to be backed up with some level of analysis. You need to look at all of the industries and products that would have become impossible, and what the ramifications of that are. Even today, you're basically proposing that entire industries, such as long-distance air travel, effectively disappear. And that sea shipping effectively regresses to sailing ships? I can't even imagine how one could begin to perform an even remotely plausible analysis, given how much each industry relies on other industries, and how difficult it would be to estimate how other technological advances would have developed instead.
