I find COBOL interesting, but then again, I also like Forth.
For example, climate change *is* happening and will probably within our lifetimes kill billions south of some latitude, which will simply become uninhabitable.
There'll be attempts at geoengineering, as "going green" was never a realistic choice on a planet as divisive as ours anyways. It was always at best a stop-gap measure. Leading climate scientists already say that a two degrees celsius goal for 2100 is dead in the water and we're on course for 3.5C, the Paris climate agreement was hoping to reach 1.5C, which already would have been bad for the world and biodiversity, but manageable. At 3-3.5C in the next decades, we'd see massive extinction of flora and fauna all over the place, yearly heatwaves in even (historically, at that point) cold countries and big impact on crops and food production, even in temperate areas. Not even talking about severe weather, hurricanes, etc.. which will become a lot more common than they already are. It's realistic to assume that these things will attempted to be counteracted by technological advancements, but the costs will most likely be steep. Last figure I read said about 20% GDP of the entire world would most likely go towards compensating for the damages caused by climate change at that point. You can imagine what that'll do to the price of the eggs. But in all seriousness, countries in vulnerable regions might collapse at that point without external help. Literally Mad Max times. If you live in a western country, you'll most likely mostly be fine, but you won't have the luxuries and givens you don't even think about and have now.
I assume things like Solar Radiation Modification (which for those not in the know, means artifical cooling of the planet by e.g. spraying reflective aerosols into the uper stratosphere so that the heat coming from the sun will be reflected back into space) Marine cloud brightening etc. are the most likely measures that will be taken. They might not even be that expensive and guranteed cheaper than just riding it out and swallowing the costs of the damages.
It's not entirely hopeless but nobody really knows what will happen or what effects this geoengineering could have in turn, as all this is highly theoretical (even controversial, for every study that proposes a method, there exists another study that says it won't work) and there's simply no real widespread experience with technologies like this, and as we all know politicans don't exactly care much about solving things that will come up after they're gone, so you can assume a lot of this stuff will be attempted last minute and in a panicked, rushed way, when it's basically too late and most of the damage is already done.
I think the non-techbro billionaires already have accepted that there won't be much after them most likely (which explains weird things like
bezos clock, and yes amazon I am aware but the dude doesn't strike me as member of the techbro culture per se) while some of the techbros probably imagine these problems to be solved by AI. They might. Who knows. Fact is that most of them already either have land squared away in areas of the world that will be the least impacted by climate change, or do things like
buying up massive amounts of farm land, like Bill Gates. He is, in fact, the biggest land owner in the US. Never let a profitable catastrophe go to waste, I guess.
