Your name is well earned! "can't cure cancers" is impressively counterfactual [0] as 5 year survival of cancer diagnosis is up over almost all categories. Despite every cancer being a unique species trying to kill you, we're getting better and better at dealing with them.

Yes, we're getting better at treating cancers, but still if a person gets cancer, chances are good the thing they'll die of is cancer. Middling results.
Because we're not good at curing cancers, we're just good at making people survive better for longer until the cancer gets them. 5 year survival is a lousy metric but it's the best we can manage and measure.
I'm perfectly happy investing roughly 98% of my savings into the thing that has a solid shot at curing cancers, autoimmune and neurodegenerative diseases. I don't understand why all billionaires aren't doing this.
Treating cancer is not the same as curing it. Currently, no doctor would ever tell you you are "cured", just that you are in remission.
