This is capability is actually really important if you take iPhone photos to commemorate family or group activities.

I've got well over 50,000 photos, and I couldn't possibly identify every person in the photos I've taken without face recognition.

Having the software and the processing power available to analyze an large collection of photos on device rather than in the cloud is a game changer.

I can see that it would be useful in a professional capacity where having 50,000 photos was part of the job. But I must ask, what do you do with those photos? Do you really cull through them and share them or use them again? 50,000 of them? It seems like you've made the case for the memory hole I was talking about.

Of course, any software always had edge cases and niche uses. My complaint primarily was that this seems to fall in the bucket of not-terribly-useful-whiz-bang-stuff that Apple (and, by all means, not only Apple) likes to include so they have something to do PR about. Animoji was definitely in this category and every FAANG company is guilty of this to some degree.

I cannot imagine that, if you surveyed 10,000 users, even one of them would list "on-device facial recognition" as a feature that they need or want from their phones.

I'm not a professional photographer. I was a digital photography enthusiast from nearly the beginning.

I kept taking photos on an SLR for a while in parallel with digital photography, then I gradually switched over to all digital. Then I stopped taking photos with a purpose built digital camera and started focusing on the photos I can take with my iPhone.

I worked really hard to drive all the digital images I have into iCloud, whether they originated on an iOS device or not. I have a decent collection of photos that came from Kodak PhotoCDs. I could have a lot more photos available in my iClod collection if I invested in a negative scanner.

My biggest use cases for face recognition are for life milestone events for other people. Weddings, graduations, funerals. People who know me often ask me to look for photos of loved ones if we've been at events together.

I could do more than I am doing with the technology. But what I can do without too much effort sometimes surprises me.

50,000 photos aren't that hard to amass if you're old. Digital photography was available to enthusiasts in 1998. If you took ~200 photos a month, you'd have 52,800 (200×12×22).

(I've personally got several times that: it's why I wrote PhotoStructure)

Undoubtedly true. I have 10,000 song files with the same problem!
