I think a lot of the goals people here want to achieve are achievable on existing infrastructure, even if the high level UX is radically different, but I could be wrong. I know some people are advocating simpler, more understandable open systems that anyone can reason about, which might be utterly alien compared to what we have now, sadly

@Dan Cook:

6) But (ironic to the label used), more intuitive and "human" than what currently exists

You mean 'alien'? Yes, I meant the word purely in the sense of "people used to existing systems will have lots of unlearning to do". Implicitly it's only worth doing if the new thing is (lots) better for humans than the old thing. Totally worth doing. Only a miniscule fraction of total computer users have been born so far, so it seems short-sighted to emphasize those of us who just happened upon the scene first.
