But that's me being a sucker. Because in reality this is just a clickbait headline for an article basically saying that the tech won't fully get us to AGI and that the bubble will likely pop and only a few players will remain. Which I completely agree with. It's really not that profound.
If you meant, "do they take 2D render frames from videogames and convert them into pseudo-3d or actual 3d where the user can tilt their head to see a different view INTO the 2D game's universe, e.g. see behind bushes just by tilting head", then "no".
Is it better to REALLY enjoy a short life or mostly enjoy a long life?
It depends a lot on how you're wired, of course. Enjoyment maximization for some people might be getting married, having a bunch of kids, being the head of a household. For others it might be accomplishing career goals or financial milestones. For others it might be adventure, to seek out new experiences, etc.
The biggest trap you can fall into is living life by the standards of others instead of your own enjoyment. That's what would likely lead to regret. I'd say to some extent (for me at least) there is a local optima to be reached where you aren't the subject of ridicule by others, but beyond that you need to take a firm stance towards identifying what brings you the most enjoyment and pursuing that relentlessly.
