I'm pretty confident that Myers is wrong on this, unless there is another information rich source of inheritance besides DNA, which Myers knows about but Kurzweil and I do not.

Myers' thesis is that you are not going to figure out by brute-force physical simulation how the genome gives rise to the organism, knowing just the genomic sequence. On every scale - molecule, cell, tissue, organism - there are very complicated boundary conditions at work. You have to do experimental biology, observe those boundary conditions, and figure out what role they play. I predict he would be a lot more sympathetic if Kurzweil was talking about AIs figuring out the brain by doing experimental biology, rather than just saying genomic sequence + laws of physics will get us there.
