@bjmiller great to have you here. I do want to ask we clarify if possible what our common ground is, and do what we can to scope this.
I would also add that I do not believe there is semantic information germane to DNA. Is it possible you mean functional information? Or information that encodes something that performs a function?
The move to syntax is somewhat helpful, but I’m not sure. Human language is much more constrained than DNA. @bjmiller you are claiming a strong parallel here between DNA and langage. No one disputes that there is information within DNA, however, what type of information is it? That is where the dispute lies.
