> brainstorming without technology.

But what are pen and paper but really old technology? :-) And given they were able to revolutionize human thought, it seems possible that other such wins are out there, waiting for us to find them.

(I do agree with the sentiment that pen/pencil are currently the best we've got along multiple axes, probably with the exception of search.)

And there is some evidence people in cultures without writing have much better memories. So no technology is without it downsides.
