0) An explicit call for weirdos thinking of entirely different non-AI technologies, ways of working, and paradigms from a VC willing to invest, grant, or introduce, in an article that also looks at a cool open-source “ubiquitous computing” package using cameras to be able to annotate and augment reality in a whole room. The conceit is “running a program from a piece of paper.” Putting it at the top for the signal boost, AI has sucked all the oxygen out of the room for most non-AI startups right
