I’ve heard this promise so many times that I’m just a bit skeptical.

Is it so unimaginable today that a 2x shrinkage is possible?

But we keep seeing these devices after multiple generations and they keep using more and more silicone so they're not shrinking that much.

The $10k figure is interesting because if they wanted to I'm sure they could sell these to tech elites and celebrities for that much (essentially, the Tesla approach). Presumably the software isn't there yet, but it seems like a missed opportunity to me - imagine getting all the A and B list celebs wearing them. Perhaps it's just not realistic until another iteration but it seems tantalisingly close.
