Someone doesn’t necessarily have to be dead for this to work either, which is a little disturbing. Or in my case I want to hook this up to my work Slack so I can take a bathroom break without someone complaining about me being AFK for a couple minutes.
It would then be another Black Mirror episode, the USS Callister one, where (spoilers:) introvert programmer Matt Damon takes DNA of his colleagues and makes virtual copies of them and imprisons them in his play universe.
Obviously the tech won't be that advanced, but having people have emotional connections to chatbots that they programmed to pretend to be their exes would be... creepy.
On the other hand I can imagine at least one Twitter user who we could put in a virtual playpen and it would benefit mankind.. Virtual Pennsylvania Ave 1600..
You can have a bot reply with "ah! Give me a second" or something along those lines while you're away. There's no need for a sophisticated solution, as people already know you're a person and are thus not very likely to suspect a bot (assuming you don't tell anyone that is).
I used to do this while botting MUDs. Immortals (administrators) would check up on you occasionally, so first my script would send a "mis-channel" communication to make it look like I was actively talking to someone else, then a quick "Ack, sorry" followed by a pause and a "one second". All while simultaneously sending me an SMS so I can take over the communication stream in person.
