EXIF data enabled some pretty cool things, like PhotoSynth [1]. This stuff looks futuristic even now, ~20 years later, basically what the Metaverse could/should have been.
I really enjoyed Photosynth. I remember coming across an account from a guy in Tehran, and there was something really moving about sitting in Pennsylvania and being able to explore his house ("Hang on, does that box say Barf?"), local parks, memorials, and other buildings, while thinking about how unlikely it was that I might ever see these things in person.
Pretty sure we can fuse those photos together into a gaussian splat and roam around freely in 3D space now, rather than just have the rectangular photos pop up, but it's still very cool tech. I remember when that came out.
