>>1422>Do you envision these waifus as having Turing-test-passing language skills?
Just as looking forward what could be most likely (from a western perspective), it'd be something like Alexa/Siri only with a different voice-engine and some more personality, that can move an avatar around. Maybe there'd/ll be simpler budget ones too with the just catch-phrases like you describe too, those could be made super cheap through just templates and distributed with like a manga by a QR code you scan.
With open source getting bigger and bigger though I'd wager it'd be pretty easy to put a homebrew locally hosted one together just with a knack for computer stuff and the patience for reading manuals. Choose a base verbal engine, etc. Modify it to the personality you want, figure out how to make it learn and stuff.>>1421
You won't see me complaining, just appreciate getting new ones for my collection!
