The Tesla bull will say that Tesla’s ML has gotten so good that these top-shelf human curators are now unnecessary, and can be outsourced or dispensed with entirely. The Tesla bear will counter that this is merely to keep up appearances; it looks a hell of a lot better to fire data curators over machine learning engineers, even if the former are still just as (if not more!) necessary as the latter.
They still have a lot of human curators (Elon said they have over 1500 in a recent interview). I imagine that these cuts are for some category of labeling that has become redundant.
