Putting the ethical dilemmas aside, I'd like to know how such bioprocessors could possibly have:

>million times greater power efficiency when compared to digital processors

if bioprocessors have to support("run" the metabolism) all their organelles, including parts that are not at all involved in the signal processing, which is I suppose >99% of the cell, compared to digital processors that we literally built with the sole purpose of performing such operations and have logical gates close in size to the single layer of atoms already? What did we miss in the design?

Much fewer electrons have to move for a detectable chemical reaction than a detectable electric current. Solid state systems are just much less efficient at computations, but they are much easier to organize.

Compare a copy operation on a DNA sequence in a cell with a copy in a memory, the cell does it extremely cheaply since it is a simple chemical reaction while the memory has to flow electrons in a giant network of nodes. You can easily copy exabytes of data using chemistry (DNA) with almost no energy.

It’s interesting that each “processor” needs a camera which is made up of inefficient transistors and other leaky electrical components and there is still a claim to efficiency surplus.
