No, Apple, please do this! My Vision Pro spends plenty of time sitting plugged in and unused. This is exactly what I want it to do with that otherwise wasted time and power.
It takes about 15 seconds to spatialize a photo, so it’s unlikely that Apple will ever ask the Vision Pro to churn in the background through every single photo in your library, but I’ve yet to see a photo that failed to become more interesting after being converted.
