We need ECC for DNA, I could probably use a deep scrub.
Isn't the reason cancer? Eventually the DNA copying errors add up.
Cancer is not fundamentally unsolvable (AFAIK?). This is a tough question to answer though. Can we prove cancer to be solvable without solving it?
There are a handful of animals, mammals even, that essentially don't get cancer (some/all large whales and naked mole rats IIRC). So that might be solvable other ways.
Nitpick, it is far less likely, but they can still get cancer.
