This “diavlog” is fascinating. They discuss the meaning of quantum mechanics, and how that relates to the issue of what a “measurement” is, and how that relates to what “consciousness” is.
I like this site’s trick of speeding up the video by a factor of 1.4, with clever signal processing to avoid making the participants sound like chipmunks. It is strange that we can effortlessly listen to people speaking faster than they naturally speak. (On first watching these videos, one doesn’t even notice that it has been sped up– the participants just seem to have had way too much coffee.)
