To put that number in context, which is just an order of magnitude, it's $5,000 for every person on Earth, about 1.5x the current US national debt, and just under the combined market cap of NYSE+NASDAQ.
As an existential problem for humanity that doesn't currently have a solution, I think that's a decent cost estimate.
It didn’t. And since I’ve learned that new technology doesn’t save us when there is an underlying social issue that is causing it. With GMO the issue is food distribution. In the climate disaster the cause is a little more complex but undeniably a few actors are making an unfair amount of money while polluting the climate for the rest of us.
I find more hope in solutions like carbon tax, international agreements, greener infrastructure, and general climate justice, then for an unproven magical technology that will be deployed on top of the existing social problems.
Never underestimate the tendency of the rich to shift the cost to others while keeping the profit. New nuclear is not going to change that.
