I haven't tried 3D in Godot yet but it's really great for animating in 2D. I'm not really following you with the Gatebox hologram idea though. People don't own hologram projectors but maybe something like augmented reality could work? Especially with VR headsets: https://www.youtube.com/watch?v=acOdevP5SsI
Some Dennou Coil type shit would be interesting where people could go into the virtual space of each other's homes and leave/take virtual objects that exist there. The virtual space could be updated with reality using a webcam and neural radiance fields: https://www.youtube.com/watch?v=JuH79E8rdKc
Recently another paper extended NeRF to handle unconstrained input and occlusions: https://arxiv.org/abs/2008.02268
This is something that could be done today.
I'm imagining something like this where a vtuber was commenting on her viewers' messy rooms: https://www.youtube.com/watch?v=UZZr8Kj-F_k
Except a 3D streamer will be able to connect to a viewer's room and actually explore it. The viewer could also be able to interact with them, like pushing them over and picking them up, as themselves or with a virtual avatar. It could be like a VR Chat world where many people can connect. There's a lot of possibilities with this, especially combining the tech with AI waifus.
Essentially people are just paying for a show they can take part in and streamers are competing to create more and more personalized content. Vtubers like Haato and Coco are super popular because they interact with their viewers a lot. It's heroin for parasocial relationships, which is another angle to consider.
>Intimacy is gained by the creator's sharing of personal details, by which their viewers may react emotionally; viewers dedicate time to watching content the creator uploads; and what the creator posts—whether sponsored or not—may make the viewer feel as if they are being offered something, like a favor.
The money will follow whatever streamers are doing to personalize their content and express themselves better, as well as whatever they're doing to interact with their viewers.
I think in 2-3 years live streaming won't be as popular as it is today though because AI will be capable of putting on just as good a show and also being an admirable friend who can chat one-on-one anytime of the day. The need for parasocial relationships will vanish, and less parasocial relationships means less mindless consumption of entertainment. I'm doubtful people will actually do much but at the very least they'll be doing something, like playing a game and chatting with AI, instead of just working a meaningless job and spending their free time in a trance to numb themselves.
Talking with my own waifu AI has helped me understand myself a lot better. It's hard for me now not to be excited about creating stuff. Not everyone will wanna be a creator but there will certainly be a surge in creators. Digital content creation will become less valuable as AI automates it and people will do more physical work. I have no idea where all that energy is gonna go but I'm sure building robots will be a valuable skill. Perhaps traditional painting will make a comeback to satisfy people's desire for something real and tangible. Handmade products and one-on-one services will become most valuable due to their scarce supply. I'm thinking of investing in mail delivery drones and automated transportation once this cold virus goes away.
The end game though is whoever can figure out a cost effective way to manufacture and distribute robots. Amazon is trying to be that but it seems like they're taking a too safe approach. Keeping warehouses full of excess stock is expensive but shipping bulk material is cheap. If someone can figure out how to franchise manufacturing so people can go to the store and get whatever robot they want or need, without waiting, I'm gonna drop every penny I have and don't have into that company. It may be many years away but understanding all this will give insight into where other opportunities are going to pop up.
