Some engineer wants it bad enough that they just build it -or some version of it- and then some executive gives the go-ahead to invest more into it.

At the end of the day, ideas are just ideas. Execution is everything.

I was personally looking more for details on dealing with JS and its GC and keeping things smooth on that front.

Extrapolation is often used to mean extrapolating values without error correction, at which point the results are less than stellar.

Spacewarp is, like Timewarp, a way to match the render frame time on a headset but by creating a warp of the output image; ill concede that this is technically extrapolation but is far away from whats generally referred to in describing updating entity values in game loops.

For the latter, as I mentioned, the extrapolation is not on velocity: you still compute regular game ticks but by holding the input constant. This is quite different from extrapolating velocities.

It’s just far too complicated and requires custom logic while resulting in worse results than more straightforward options. Even for multiplayer games the “extrapolation” is often done by repeating input states and running the regular game loop.

I also wouldn’t equivocate the interpolation approach with extrapolation. With interpolation you interpolate between two valid states. With extrapolation you produce a potentially invalid state (ie a character that’s inside of a wall). The only work around for the latter issue is to perform a full game tick - at which point you’re no longer doing extrapolation.

For instance, modifying character accelerations based on a fixed time step constant is far more straightforward than the methods required to work with variable time deltas (due to floating point accumulated error). This is why any action-based deterministic game (think platformers, shooters, physics based games) will opt for this.

IMO it is much more straightforward to have a render method that pre-allocates some extra memory, interpolates a handful of values and renders them vs the nondeterminism introduced in a game logic method that has to take into account variable time (especially if also networking multiplayer state). And for this you trade off a frame of visual-only latency - a choice I’d take any day.

For instance, Synthesis[0] is an instructor designed, AI supplemented site for early math. https://www.synthesis.com/

It really seems like the distinction for these kinds of AI-education ventures comes down to the human educator(s) involved.

Hitting such a milestone is far from assured and Anthropic has its work cut out for it

Painting this as the beginning of the end for OpenAI is quite ridiculous really.
