ok April 22, 2013: this is prior to the Jeff Hawkins AI video from May 2013; all my research, according to various AI measures I stick through, seemed to have been around AI: cognitive science, mathematics, physics, despite deep dives into each, they seem to add up to AI. I remember a Jeff Hawking video inspired me in May 2013, but I also remember this in April 2013 about salience; so now to probe a little prior.
