SF fans remember idoru from William Gibson's 1996 novel of the same name, which popularized Kyoko Date, a computer-generated person created by Visual Science Laboratory in 1996.
"...She is Tei Toei. She is a personality-construct, a congeries of software agents, the creation of information-designers. She is akin to what I believe they call a 'synthespian', in Hollywood."
Update 18-May-2021: See this earlier reference to the idea that computers can be used to create digital persons; Adam Selene from The Moon is a Harsh Mistress (1966) by Robert Heinlein.
End update.
