No, but a philosophical argument that showed how it was impossible would be almost as useful. You can just give someone a magic feather and let them believe they have become something, which is sufficient for many purposes.

Remember that in the Matrix story, a world in which they could download skills from the simulation and instantly become things by essentially just imagining them, so long as they stayed within its confines - was the world they were trying to escape. If you tell a 5yr old that their crayon drawing is beautiful, they become an artist, and for most people, that pattern doesn't change for the rest of their lives unless they become disillusioned and pursue their destiny as an existential hero.

Maybe there could be some neural interface that lets you transmit and replay brain activity through other bodies faster than language does now, or muscular electrostimulation that simulates say, deadlifting, but just as having a music collection doesn't make you a musician, I'm with Feynman in that I don't think we understand what we don't ourselves create.

We have actually had muscular electrostimulation devices for quite a long time. I believe they work quite well to get stimulation when injured.

In general though anything I have read says they work well even if not injured. They have just never caught on the way lifting weights has.

Knowing how to do something doesn’t live outside the brain.

You can erase entire categories of knowledge by damaging the brain in particular areas. There is no reason to believe the opposite is not true.

Therefore it is a matter of modifying the state of the brain to learn or know something.
