Oh no! I really believe sandstorm (or something like it) is what we need the future to be. Rather than having everything get sucked up into Google, Facebook, Apple, or these other few centralized services, imagine where everyone has a personal (or family, or church group or whatever) server, and they can one-click install their email apps, their document apps, etc.
The basic issue is that everyone wants "cloud" apps, so that their emails and chats appear on their phones and their tablets or home computers. But unfortunately it seems we leapt straight from the PC paradigm where your email is stored on your computer straight to the "centralized, 3rd party cloud" paradigm, where Google owns all your stuff. But with a "cloud" that you still control, tough problems like end-to-end encryption fall away, since it only needs to be encrypted from one person's cloud to another, while the messages themselves could be synced between all the user's connected devices.
Linux was a beautiful, world changing thing. If we could establish an open-source platform seeking to replicate a lot of things Google and Facebook do now, but without the privacy implications, that could be equally world changing.
Sandstorm, at least as far as I understand it, definitely has the vision right, so I'm hoping despite Sandstorm for Work not panning out, the technology will continue to grow.
