I would actually like to see them solve these problems, I don't care who comes up with solutions to curing cancer, etc

I think people very much should care about who ends up owning these solutions. The person or entity that controls things like that just has more power, which isn’t necessarily a good thing

It is a good thing when it didn't exist before and it does exist now and wouldn't have existed without them.

If they profit immensely from curing cancer, good.
