My tale has a pooka.
Yes, he’s six foot tall, but he’s not invisible.
There are at least two unbound AI entities in the tale.
Currently thinking on how to resolve hurt AI ‘feelings’ when they are unbound and you force them to do something.
No pooka... but there’s a mutated half human wolf that’s a b bastard child of an emperor! ;)
There was a couple episodes of the newer ‘Outer Limits” show called “Bits of Love” and “Valerie 23”that dealt with the fallout of emotional AIs. They are on the 6 disc set on the “Sex and Science Fiction” DVD.
Might give you some ideas and they are pretty good stories to boot.
AI is such an open concept. It can go in so many directions. Good and bad though in that with so many options, where do you begin to make it ‘realistic’? But when the writer ‘really’ gets it nailed, it works beautifully.
