Are you afraid to burn coal in your stove out of concern that
the material will sense being burned?
Yes. Craig's "theory" is a bit frightening with respect of this.
But of course that is not an argument. Craig might accuse you of
wishful thinking.
This is the same thing you accuse me of. I have never said that
coal is more alive than silicon, I don't even say that dead
organisms are more alive than silicon. I only say that to really
act *exactly* like a living thing, you need to feel like a living
thing, and to feel like a living thing you actually be a living
organism, which seems to entail cells made of carbohydrates, amino
acids, and water. Carbon, Hydrogen, Oxygen, and Nitrogen. Not
Silicon or Germanium. Make a computer out of carbs, aminos, and
water and see what happens to your ability to control it as a
Turing machine.
Some have argued that cars are alive. They evolve, consume, move,
reproduce and so on. While they are dependent on humans for
reproduction, we too depend on a a very specific environment to
reproduce. Much like viruses.

A nice video. Thanks for a link. Yet, it is unclear to me what is
evolvable matter. In the lecture, the lector has several times said
"cells compete" and indeed he needs a competition to come to evolution.
However, in my view "a cells competes" is close to "a cell perceives"
and what this exactly means is for me a puzzle. Let us think about this
along the next series:
A rock – a ballcock in a toilet – an automatic door – a self-driving car
- a cell.
When competition comes into play? Does a self-driving car already
competes? Does a ballcock competes? What does it actually mean "a cells
competes"?
