Yeah but can we not give the control of the entire planet's climate to Elon Musk's AI?

Yes, but there are far easier and cheaper ways to go. Dude must have just read about using things from space to control sunlight input and thought he's such a genius surely he can figure it out. I guess he skipped over all the debunking that such ideas get.

And crucially, once we jump on the geoengineering train, we better not stop. It will only slow things and buy more time, but if we stop after beginning, the spike will be catastrophic (probably, there's still so much we learn, but it won't be a solution). But we will go that route, because economic health is far more important than anything else, and never plateaus by its very nature. There must be growth, or it all crashes down.

Stop polluting and plant trees.

Rocketing giant mirrors is not only stupid but also temporary.

Yeah. Talking about geoengineering is great.
