Here is an unexpected one: Russell Ackoff. He gave talks through
  his life on Systems. Cybernetics. How things functions as wholes
  and not parts. I snagged a clip from a longer talk he gave and
  highlighted a few bits because he so impressed me.

  You have to get over the bad video quality. It's not polished
  like Ted Talks are. It's an older video. But just listen. He
  doesn't get woo mystical about any of it. He's so matter-of-fact
  and yet I still find myself going, Yes a lot.*

  I only discovered him about nine months ago, but it confirmed a
  lot of what I suspected. It's a problem we don't address even
  today, not very much... not without lots of woo and mystery.
  It's worth 5 minutes.*
