How would you implant the digital personality into a flesh body. Also, the way current machine learning large language models (what is currently called AI, and for this case, I think there must be a distinction) generate responses are not the ways a sentient generates responses, so the created being would not have the personality of someone, they would be closer to someone doing an impersonation. To see what I mean, tell ChatGPT to act like a celebrity you are familiar with, and talk with it over a long period of time. It will eventually get worse, and worse and worse as the conversation continues.
