Bs. People do different things. But nobody can sit around wallowing in the VR. Having seen what death of my cousin and grand parents did to the family, moving on helped every one heal in a way. VR would have been a torture to live in.
Perhaps starting your comment with "bs" is not a surefire way of getting your thoughts considered seriously..

You are taking the worst possible interpretation of my comment. I was responding to literally the aspect of the GP that said "mourn.... move on" It is a factual matter, easily discovered through simple searches, that non-Western cultures often take a different approach. Including, literally, ancestor worship. I am not making a judgement on which is better. I believe there are multiple healthy ways of dealing with gri…

My gut reaction to 'recreating loved ones in VR' is that it would be torturous more than soothing. Once a person dies, they're gone. The world is different, and nothing will bring them back. Spending time with a simulacrum isn't really spending time with a loved one.
Don't knock it til you try it? I mean, already in recent years people have made some very low fidelity 'resurrections' and gotten some measure of comfort from it, never mind the many years of history of people who visit gravestones to 'chat' (some even believing they get replies to some extent or another). When markov chains were hip, "talk with Charles Dickens!" (play with a markov model trained on his works) was at…
Will the simulacrum age? Will it change? Will it ever surprise me or intrigue me? And if it does, is it something the dead person truly would have done?
It's sort of like a photograph; a photograph seems to capture reality but all it shows is some abstraction of a physical reality at one point in time. The photograph tells me nothing about the current reality of anything depicted within.
A simulacrum gives me the person I knew, when they died, and that's it. Perhaps comforting and interesting, but ultimately unfulfilling and unsettling I would imagine.
I am kinda skeptical, AI demos are impressive but the real world results are underwhelming. How much it resources it takes to generate images like that? is this the most ideal situation? Can you take images from the web and based on metadata make a better street view? With all this AI where is one accessible translation service? or even an accent-adjusting service? or just good auto-subtitles?
as someone who works in both AI and filmmaking, I remember losing my mind when this paper was first released a few weeks ago. It's absolute insanity what the folks at Nvidia have managed to accomplish in such a short time. The paper itself[0] is quite dense, but I recommend reading it -- they had to pull some fancy tricks to get performance to be as good as it is! [0] https://nvlabs.github.io/instant-ngp/

I think the cool part is that a neural net can learn to produce (R,G,B) from (X,Y,Z,angle) by using a clever encoding trick with sin() and cos() for the input coordinates. And the fact that a neural net can be a frigging JPEG in 3D.

You’ll find this is true of all NeRFs if you spend time playing around with them. If a NeRF is trying to render part of an object that wasn’t observered in the input images, it’s going to look strange, since it’s ultimately just guessing at the appearance. The NVidia example in the link has the benefit of focusing on a single entity that’s centered in all of the input photographs - the effect is much more pronounced…
I know when doing typical 2D video based rotoscoping it is possible to use frames from before/after the current frame to see data that is being blocked in the current frame. It's also common in restoration when removing scrathes/hair in the gate/etc. To that end, I wonder if exporting a similar bit of video from that same path exported as stills would be enough to generate the 3D version.

Self-driving car companies are already working on this. Check out: https://waymo.com/research/block-nerf/ NERF is a very active research area, and the progress from 2020 to now has been nothing sort of astonishing. In 5 years, I expect there to be fully generative NERF's in research i.e describe a scene, and a NN produces a full 3d scene that can you interact with.
Can it be done with Google's existing Street View data?
Nvidia is really turning into an AI powerhouse. The moat around CUDA, and how those target customer aren't as stringent about budget, especially when the hardware cost is tiny compare to what they do. I wonder if they could reach a trillion market cap.
it's not a matter of "if", but "when" they will reach a trillion dollar market cap.

> it would be torturous more than soothing Relevant Asimov story: https://en.wikipedia.org/wiki/The_Dead_Past
Reading about The Dead Past tho, there's a good deal of overlap with the plot device of "Devs", a periscope into deep history, but which Nick Offerman's character uses to re-live moments of his daughter's short life, as Asimov's protagonist does.
