I agree on the molecular computing. The resources are there. Not sure though how one would go about calculating the evolution parallel algorithm OPS, it would be different than just cell reproduction magnitude. Still though I don't agree on your initial numbers estimate for AGI. A bit high perhaps? Your numbers may be able to be trimmed down based on refined assumptions.
