It's bad that a few people are making such a gamble on behalf of billions. That could work if climate change were literally an asteroid about to strike the Earth and AI was the only thing that could figure out how to alter it's course before then.

Because then it becomes a decision the entire planet should be making over time, not a few tech billionaires and their friends in government.
