The infrared light thing seems foolish unless the other person knows you are trying to find them and removes their phone from their pocket or purse.

AppleGPT is badly needed but they cannot break what Siri does well and that’s likely why this is so delayed.

That HomePod camera accessory thing would be much more useful if it incorporated a StandBy like information display.

I cannot imagine that color matching band idea going anywhere, but the watch camera seems even less likely as it would be far too clumsy as described.
