There is also an animated show called Pantheon that deals with “uploaded intelligence” and the process is likewise fatal. I can’t recommend it highly enough. It had two seasons and the story was completed.
Pantheon is great. I had almost given up on good SF in visual media when this was recommended to me.
Season 1 was great. Been going steeply downhill since then. But yes it does have this premise.
What's the name?
Upload. It’s hilarious and has totally put me off the idea.
