I personally hope that the output ends up being systems that are good for individuals with their own dynamic lands at home, not just strong group collaboration. I know there are already people who have setups done in coordination with the Dynamic Land team.

I've visited dynamic land also, and the vision of this more tangible visible computation is bigger than the incarnation/progress last shown.

I'm a fan of Darklang's goals too. But I do think Dynamic Land is targeting more approachable, teachable, and communal computing. Darklang is going to be more for professionals making backends and doesn't target any user facing audio/visuals whatsoever. It could in the end of course, so I hope it does well as an effort too.
