It's 2023. We have incredible technology like DALL·E 2 and ChatGPT, but iPhoto and Google Photos still can't collaborate on a shared photo album. Texting is even worse. Then there's collaborative playlists, collaborative note-taking, videoconferencing, the transmission of large files, and so much more. Any of these things can be achieved if all participants are using the same software, but different applications with similar capabilities refuse to work with one other. If I use Spotify and you use Apple Music… too bad.
This is understandable, but so unnecessary. I can't even imagine how much time and energy we lose to this segmentation. Interoperability matters.
