Looking at all the outdoor scenes that you can walk around, I wonder how long until we start seeing this in places like Google Maps/Earth, as a replacement for the low-res 3D renderings we have now.

I guess the number of samples required to generate a GS is the constraint now, but maybe that will get solved.

Google already has some splats on google maps,

rendering them is also non trivial from what i understand, since the millions of indivudal point positions need to be recalculated all the time while moving
