For people who like a concept more than practicality. There’s maybe a handful use cases that this specific device fits in that isn’t covered better by existing tech, but I guarantee if that thing actually gets kickstarted and arrives severely delayed in several years, it’ll show up in a couple YouTube videos with people sort of uncertain what to use it for, and in the vast majority of cases it’ll end up in some drawers after having been used a few hours tops.
Mastodon and the fediverse are nerd shit with massive usability issues. Even I gave up on Mastodon and I would consider myself far more willing to put up with shit than the average user will ever be. The mass will - never - migrate to the fediverse and in many ways, especially looking at moderation issues, that is probably a good thing.
