The future of renewable energy is very promising. It’s easy to miss how fast it can turn around when growth it grows so much year-to-year but starts at a small place. Keep this kind of growth up and the grid will be clean a lot faster than seems possible.
Beyond solar I’m also very hopeful about offshore wind efforts in the US.
We still live in the same society as others. People often adopt the cultures and ideologies of where they end up, or at least move closer to it than they were before. If reddit shifts its userbase to the right — even if the net effect is from “very very left” to “very left” — it will impact the lives of all of us that live in societies with large numbers of people using that site, as it’ll filter down into our politics. Even if we don’t interact with them.
For a long time, the “default” ideology of the internet was on the left. As internet usage has become dominated by a handful of sites owned by megacorporations, there has been a not at all subtle effort to nurture a conservative ideology on those sites. Stuff like reddit holding off on banning the Trump sub for however long or twitter refusing to implement their hate speech detection because it correlated too strongly with conservative politicians (not to mention what Musk has done there). I don’t think this is an accident.
Aviation is one of the smallest contributions to greenhouse gas emissions as-is: in 2016 it was 1.9% of global emissions.
The danger the rich pose to the planet isn’t being first in line for the second generation of supersonic transoceanic flights.
The danger the rich pose to the planet is them keeping coal and natural gas plants open longer because they personally profit from it. It’s them keeping their taxes low, reducing our ability to fund renewable energy. It’s them fighting tooth and nail against any new energy efficiency regulation (remember the incandescent lightbulb ban fight?) because it “hurts profits.” It’s them fighting against public transportation.
This? This isn’t even in the top 50 of their ills against the climate. The hate for the rich is well placed. Applying that hate to basic science is dangerously misplaced. The rich love when people push-back on funding science efforts.
Faster transportation is quality of life too. Just like cars were, or railroads before them. Yeah, this one is currently worthless for anyone that isn’t rich. But if it proves successful it will become useful for more of us. Like you say, there’s also just the material and other sciences being done to make it possible that will filter out elsewhere. So much of early space exploration was Cold War dick waving, and now think about how much we rely on satellites. I couldn’t navigate anywhere without GPS, personally…
People here take their hate of the rich (which is well placed) and aim it at all the wrong things. Don’t like the rich? Tax 'em more. That’s what I want. Higher income taxes and even a wealth tax on the top. And way more meaningful inheritance taxes. Instead they’re bitching about investments in science.
Technology filters down. Once upon a time only the rich could afford corrective lenses, but that wasn’t a waste of resources. How many of non-wealthy people will read this comment and wear glasses or contacts? I do. BEVs were limited to the wealthy at first too, and now are solidly affordable to much of the middle class: dependent more on their access to charging and their driving requirements than on their budget. The first residential fridges cost more than a brand new Model T when they came out: the inflation adjusted 1922 price was ~$13,000 today. Was inventing fridges worthless?
It’s NASA developing new technologies. New stuff starts off more expensive, which means it will start off limited to the wealthy. If you don’t want any new tech to come out that starts with rich people being the primary users, then you should go find your local luddite club to join.
Do you have data on that? A modern nuclear power plant is going to be in the 500-1000+ MW range. I have a hard time imagining that even operating at half capacity that they do not offset the carbon used for concrete within a relatively short order. But if that is in fact the case I’d love to see data saying so, so that I can correct my thinking.
