I wonder if some kind of wearable fMRI could be used to just avoid the whole thing. Seems like the universal rule of tech is that any insane idea within the laws of physics is eventually possible, but anything to do with biology is 50x harder
If we discover room temperature superconductors this might be in the cards. Lots of exotic stuff becomes possible then but no one knows if it’s possible to have room temperature superconductors.
