Has anything serious changed about photos in the last 15 years? I've used it before then and can't really think of anything apart from embedding search and random reminders. But those are really small features.

Well Google photos wasn't released 10 years ago, so ... that at least?

Unless you're thinking of Picasa, which is a whole different conversation lol

I mean, afaik the standout feature of Picasa was shared web albums where you could invite people to add photos and permissions were managed via Google accounts, so, it's easy to confuse the two. From memory the only thing that changed when moving from Picasa to Photos was that I no longer had a desktop app where to keep photos on disk + Picasa had a neat map of geolocations (maybe Photos caught up or can you still not view photos on a map? I know apple does this, I just use ACDSee now and keep it offline)

Yeah, I'm treating Picassa as Photos 1.0. Apart from the stand-alone app it's basically a continuation with data migrated by default.

Google photos is awesome. I genuinely love it, I've been uploading my old travel photos to it and every few days my phone reminds me of some old memories.
