> Bill Gates accepts climate change is happening, that we should do something to avert the problems, and thinks that we can do that as a species. He thinks that renewables and EVs etc. will all help, but aren't enough and we should look for newer solutions. He has invested in multiple different solutions, presumably because he thinks some will be needed but not all will work. > > So he's a pessimist, pessimist, optimist, optimist, pessimist, optimist, optimist/pessimist. And that's one person on one idea.

That's a really interesting way to slice and dice it. When I read your first few sentences that's not how I interpreted it at all.

I got fact, fact, optimist. Optimist, fact. Fact, optimist, optimist.

But I'm not convinced that's a better way to go about it. What is likely needed is each of those chunks to be taken into context and when I look it at that, it's really "here is a problem and a solution to move things forward." To me that's optimistic. If it were pessimistic, I'd expect it to be "here is a problem and there's nothing we can do about it."
