One thing is painfully obvious to me, we will have an even more significant energy crisis in the future. Even without the Russian events this year, energy has been significantly under invested for almost the last decade. It takes a long time to turn the ship. Largely shutting the world down for months (years?) in 2020, suddenly pushing green fuels and making fossil fuels 'evil', and then the more recent Russian horse-crap has only accelerated the issue... but either way, we were going to have an energy crisis in the coming years/decades. Oil exploration has been largely under funded at last since 2014, the fossil fuels themselves are becoming more rare over time, and we have to work harder and harder to extract them, all while they are being demonized by governments (making them that much harder and more costly to extract). At the same time proposals to push electronification for everything, without a satisfactory infrastructure in place to support it. Nuclear MIGHT be a clear path forward, but even it would take substantial investment and decades to fully implement, with no clear plan to do so today. And while there might be some improvements on how to handle the waste, there will still be some significant issues regarding that in the future as well. This will only be compounded if nuclear is utilized much more so in the future.
For the last decade or so I have built energy redundancy into my house. NG, wood stove, pellets, MS heat pumps, and this year adding solar (enough to survive off grid), as well as adding insulation all around the house to make it that much more efficient. I suspect I'm now far more insulated (no pun intended) from the coming energy crunch than the masses, but I still don't think I'm fully prepared for a world where even the more basics, such as food and water, could very well become an even bigger issue.
At the end of the day, I think it's a little extreme to be a laser focused and paranoid "prepper", but OTOH it's probably foolish to not have at least some decent form of "plan B" ready for basic survival (ideally with some level of comfort) in a rapidly changing world. Worst case, you don't need it, save a few dollars, learn new things, do your part to contribute to the planet, all while being more comfortable.
