A good chunk of Black Mirror episodes deal with the ethics of simulating living human minds like this.
But yeah, it's too gratuitously bleak for me. I feel like that's a crutch, a failure of creativity.
I love it too, one of my favorite episodes of TV ever made. That being said, the ending wasn't all rosy. The bank of stored minds was pretty unsettling. The closest to a "good" ending I can recall was "Hang the DJ", the dating episode.
