Re-reading these essays. Link takes you to 4th of 4 but first 3 embedded. I found it easier, if more expensive and resource-heavy, to print them and read them whenever I have a minute. Miss the links and videos that way, but my ancient brain works slowly and can only take so much stimulation. Really impressive work with quite profound implications. Although,as Dave says, no one is likely to pay a blind bit of notice. Which kind of makes his point.
