I don't mind if steemit dies, the other front ends are a lot better anyway (my favourite on desktop is SteemPeak which I'm using right now and Partiko which I'm using on mobile).
Unless you meant if Steemit Inc decided to run off with their (sizable) share of things, then maybe we might be in trouble? I should probably have some idea but I'm a bit clueless, I've just been hanging with my friends here and posting the same repetitive content XP I'm pretty sure at this stage steem can float away on its own if it needs to.
