> As time has gone on I felt like we had lost some of the magic of easily sharing your machines and your creations with other people. We have a ton of services where you can now deploy and share your creations, but we've moved further and further away from direct sharing.

This is interesting, as it hasn't been my experience on the hobbyist side (game servers, personal projects, etc). ngrok, localtunnel, tunnelmole, rathole, tunnelto, zrok, et al. If the use case is just sharing something you built thats behind NAT / on a private subnet, there is no shortage of solutions.
