These Early Access survival titles are more like SaaS, in my opinion. It's not really about hitting 1.0 and then wrapping up and going on to the next project (for better or worse, and there's definitely plenty of both).
Ark may not be 1.0, but there was plenty of game there for me to have a lot of fun with it a year ago. Fortresscraft Evolved is not considered in Early Access but is also under continual development thanks to Patreon funding. People have been playing Rust since 2013, but it is still considered Early Access.
I guess my point is, I think these games need to be viewed from a different perspective.. The question isn't "Is it 1.0 yet?", it's "Can I have fun with the game right now?".
