Get LLMs to hillclimb your wife's treatment. The target isn't exactly verifiable but you could iterate on ways to add verification signals. There's a huge difference between asking an LLM: "hey claude, my wife has cancer, I want your help with x,y,z", which mode collapses it into extreme over-caution; versus setting up the problem like an eval, which sends LLMs into a frenzy trying to solve it no matter what.
Second thing I can share is the man who created an mRNA vaccine for his dog Rosie's cancer, and it worked! https://news.unsw.edu.au/en/meet-the-man-who-designed-a-canc...
LLMs aren't genies
