It can literally only write words. And it cant even do that well. It only does well at coding and math because it can be brute forced against compilers/verifiers. There is no compiler for the human body, the closest thing we have too it is death. The chemistry and physics going on in the body is much more complex and mysterious than all this math and computer science LLMs are helping with.

LLMs aren't going to make you live forever. This is a marketing scam. They are stateless statistical models that spit out words. Thats it.
