If they profit immensely from curing cancer, good.
Maybe it is, idk, you may be right. But I think it’s something people should care about.
If AI companies create better treatments they'll offer them to people who pay for them. So wealthier people will have better cancer treatments. If they can make them inexpensively, then a broader audience also gets treatment.
Eventually they lose IP rights and they become generics and the world gets better cancer treatments.
In all scenarios having them find better treatments benefits humans with cancer more than if they didn't.
I don't like trusting any organization, corporate or governmental, with control over people's lives, but it's obvious that we're not going to get cutting edge medical treatments without these organizations.
