Jason Cawley gives us another immense post with a semi formal argument about quantum computing and the universe as a quantum computer. It is a response to Hector Zenil’s interactions/postings with/about Seth Lloyd.
I’m in agreement with this:
At some point you have to go look at the actual world. And when you do, you will find yourself at the bottom of a well looking out through a straw at an immensity. Honesty and rationality start with an elementary humility in the face of this inescapable fact. This does not mean you can’t know things; you can. It does mean you can’t know everything.
It’s a challenging post which befits the challenge of uncovering the limits of knowledge, quantum computer and “just how does this universe thing work.”
We can’t know everything, but there’s no limit to how much we can know (meaning, there’s not enough time in our lifetimes for us to reach even the formal limit!). Chew on that.
