Yea this is economics, not tech.
We also don't build carriages as well or have an army of craftsman doing it, but it's lost/regressed because there's no economic incentives.
We build car/truck bodies, which are much the same --- the family station wagon when I was growing up had a badge in the doorwell, "Body by Fisher" w/ an image of a carriage, that company having been a carriage-maker which transitioned to car/truck manufacture.
And we do pretty much the same with stonework now compared to the ancients.
There are a few that know how to do it by hand, but mass production has evolved.

...and we're so damn good at it that we can grind a complex shape to micron precision for the purposes of a shitpost -- which then gets automatically blasted to a million algorithmically selected interested parties for the amusement of all.

I have nothing but respect for the skill and professionalism of the ancients, but I find it extremely distasteful when someone tries to express this by putting down their modern counterparts.
Current methods of cutting pretty much anything including stone are absurdly more precise than what Incas and Egyptians had. We can cut stuff like diamond lenses down to 10-100nm roughness.
