If I could figure out how to program it, I could be a mega-millionaire. Make a virtual girlfriend/wife that lives around the house. Give her a good voice assistant personality. She can watch netflix with users on the couch, and they can pay buku bucks for some skimpy outfit DLCs. The thirsty dudes would love it. Make it so they have to do shit with her to level up to unlock more outfits or sex positions and such. Could even have her sleep in bed next to them. A waifu pillow with those 3d tracking marks on it. Just gotta figure out how to get physical interaction. Maybe a fleshlight with those 3d tracking marks on the outside. Think of all the money that could be had with accessories. Link her up with Alexa and Google Home so she can talk to them without their headset on like the movie HER. Integrate her into a phone or watch app so they can talk to her at work or out and about or text message her.
Could even have a premium version where real women could get paid hourly to be the voice of the girlfriend. User could put cameras around their house and get a 3d scan, and that could go to a VR set that the RL woman wears and can move around that persons house. Hell, porn ideas aside, users could hire people to eat dinner with them, or have a dinner or watch a movie with distant family members as if they are in the same room. You could even turn it into the next version of online dating. AR is the next best thing until hologram technology actually works.
