If you mean a stumble in the sense that I'm not truly aware of the implications of what I'm proposing, that's not really the case. I personally believe we could be yet more ambitious than what I am describing here, but I realize that most people aren't going to be on board. So the next best thing is to propose a different framework of looking at the problem and a different methodology for looking for solutions. A dedicated device would be incremental, yes, but what matters is that if we unlock the capacity to think towards this sort of innovation the big changes will follow naturally.

Just to clarify, I meant “stumble” as in it seemed to be somewhat stream of consciousness; just happening to end up at “give everyone a home” rather than planning a route there from the opening sentence.
