I would say if you could solve just those three problems, you would have so much money thrown at you, it wouldn't matter what society thought.
People should then be throwing all their money at AI and Quantum computer companies, and research, and development. The faster we get those two things the faster we can put them to work, coming up with models, and with solutions to these three and many more vexing conundrums.
But alas, the public don't care about actual solutions; they just want to do the quick feel good band-aid solutions such as marginally lowering their carbon footprint, which is next to negligible.
So would you invest if it this protocol had Artificial Intelligence , integrated to be used to solve world hunger / climate / cleaner water...
Would you invest then?
