Apple has the same functionality and does all processing locally, though I'm not sure if that's an argument for or against your assertion that it doesn't scale.

It does work, but it's not nearly as seamless as Google's cloud implementation. I have many tens of thousands of photos in my Apple Photos library and I think it takes over a month to process everything if I start from scratch on a new computer. Somehow it seems much faster on the phone, and I'm not sure if that's because the processing is better hidden from me, it's much more efficient on the custom chip, or maybe a bit of both.

The later, a bit of both. It’s also probable that your phone is turned on and plugged in more often than your computer (especially for laptops).

Regardless of how it's done, I treasure my iPhone performing the facial recognition of my Photos library locally (10+ years of photos) as I continue to extricate my data from Google services.
