I’m generally skeptical of digital people, but I think you can almost certainly say that meaningfully recreating a person without access to brain scans far beyond existing technology would be impossible. Even if you accept the philosophical assumptions necessary to believe that a recreated digital person is morally continuous with the person it’s based on, the only way to recreate a digital person without access to that kind of scan is by reversing entropy and recovering the lost information. No matter how many possible versions of the person you make based on incomplete information, you could never have enough compute to find one that matches, or the information to identify which one is correct. There are 8x1067 ways to order a deck of 52 cards. How many viable networks do you think there are of 82 billion neurons?
