It is cold for me to not want to concede everything to billionaires to cure a disease? You are short sighted, as I would argue the reverse is cold.
"Concede everything" is way too vague to argue against, but I'd be more than happy if whoever is behind the tech to cure a horrible disease like Alzheimer's is made filthy rich for it.
That's a fallacy. You're assuming we all agree that this is going to happen. I don't agree. And I think AI will drive a huge amount of innovation that is going to make almost everyones lives better.
