It's been around for 7 years now with over 1B users and is directly monetized by storage space. I'm a big Apple ecosystem person and even I use Google Photos instead of iCloud so I would bet on it, yes.

Disclaimer: I work at Google. Opinions are my own, etc etc. I have 0 to do with the Photos team.

Google Photos is an amazing product, it has an amazing offering and works extremely well. It's also extremely popular and integral to the Android ecosystem. I'd absolutely bet of it not being shutdown in the next 5 years, yes.

one of the few I would, yes.
