"governments need to act to put a cost on negative externalities, which in turn will allow a market to develop, leading to private companies provide solutions for said market." when you say it like this, it def sounds like a more reasonable proposition to debate. i mean we already basically capture that in our military R&D, don't we? like didn't they say that climate change needs to be contained to reasonable parameters and stuff, years ago? i'm sure they're funding lots of work and making contracts available. it's a matter of nation defense after all lol. and didn't Elon announce $100 million for a proven idea that works for sucking carbon out of the air? https://www.xprize.org/prizes/elonmusk https://www.xprize.org/prizes/elonmusk seems like both public/private are poised to have an interest in solving big problems via technologies and that's great. that's about the only existential or national defense externality I can think of that needs more funding. and it's already picking up steam. AI research is getting a boost too.
