I think Kuzweil knows that chemical biology is inherently non-linear. And I think he knows how fetal development works. I agree that blueprints are static but so is DNA without a cellular mechanisms to start the process. In sperm and egg banks the DNA is practical frozen. The blueprint is there but the process is stalled and hasn’t event begun until the sperm and egg come together.
PZ Myers doesn’t understand that Kuzweil is not talking about compressing “the process” but that the DNA information can be compressed then uncompressed. As I said before this is only for biological brains.
