One thing I liked in 2049 was now they made the holographic projector seem more mechanical and less hand wavy with the roof attachment tracking along with the girl. Makes it seem more like something in reach rather than pure scifi.

I think what Blade Runner 2049 got wrong was the way they depicted having sex with the Joi instance. I assume in 2049 we'll either have Neuralink available to enter a virtual world (à la VRChat) where we can do it more realistically, or we'll have the ability to buy full sexbots and put the Joi instance in them.

We'll likely also have virutal brothels using AI along the same lines.

No need to create environment when the neurons can be stimulated directly. This scene from Pacific Rim Uprising movie freaked me out.

Dr. Newt (Charlie Day) heads home after a tough day at the office to his wife 'Alice'. Turns out, 'Alice' just happens to be a massive Kaiju brain in a tank. [0]

You should see the remastered THX1148 for the VR future.

That has more to do with Ana de Armas looking how she does than anything else. I'd have dated her as a Harlan Thrombey's nurse too.
