My takeaway is that Sussman is looking at his field after a lifetime of contribution. He's looking for signposts on where we can go next. He's not valuing one over the other, but looking at the brain and saying, "Here's something that exists that's operating on problems in a way we can't begin to approach using current software/hardware techniques". He sees some hints available to us in the noise reduction things he talks about at the end. In that way, the talk is more him challenging the audience to question our approaches and implied constraints rather than him trying to present us with an answer. It's one of my favorite videos (the way too loud HI at the beginning, notwithstanding).
