Better be careful with that...

From "Bicycle Repairman", by Bruce Sterling (1996) (This is a spoiler, BTW!):

"The mook speaks just like the Senator did, or the way the Senator used to speak, when he was in private and off the record. The way he spoke in his diaries. As far as we can tell, the mook was his diary.... It used to be his personal laptop computer. But he just kept transferring the files, and upgrading the software, and teaching it new tricks like voice recognition and speech-writing, and giving it power of attorney and such.... And then, one day the mook made a break for it. We think that the mook sincerely believes that it’s the Senator."

Oh, and just note that this was way before Black Mirror.

I mean, off topic, but it's not like any (citation needed) of the ideas in Black Mirror are original; it repackages existing ideas and tropes in a modern context. It does an excellent job of that, but it's a bit disingenuous to use it as the golden standard for whacky scifi prophecies.
