This makes me anxious about my long time Gmail address. Back then I got it just because it and Google was cool, and their services had a good reputation. It was a different Google back then. If they had launched it this year I would never have got one because chances are it would have been cancelled by 2025. Gmail is really the only valuable thing that actually ties my life to Google. And it's not that hard to replace, but just a bother to inform some people and update account details.

As someone in a similar spot with a GMail account I've been using since they were invite-only, I've started using Google Takeout to back up an archive of all my data from Google's services a few times a year.
It's not perfect, and I'm thinking more and more about moving to a paid service, but this at least gives me some peace of mind that if one day I run afoul of Google's AI bouncers, I won't lose a decade of info overnight.
