As far as other media within Rick & Morty, the Second Life-like "Roy" is something that I wish could exist. Immersive gameplay, accelerated time, tangible experiences, and endless possibilities.
And assuming that human beings work on it imagine what skills and abilities you could acquire.
It's kind of like the piccolo thing in Star Trek the next generation with picard. Like imagine playing a video game and then coming home and being a rockstar guitarist on par with Slash, or getting 50 years worth of meditation and monk training in before work on Monday on top of a second lifetime full of martial arts training.
Something like that would be so revolutionary it would dwarf any kind of nonlethal AI apocalypse in comparison.
There's already a company looking to do just that, although they are focused on using it as a replacement for prison. i.e. instead of serving time in prison, the tech implants traumatic memories into your brain that are related to the crime. It wouldn't be a far leap to implant desirable memories, though I'm not sure it would actually help you do something like learn an instrument, as muscle memory isn't something you can implant (maybe?).
