The "so what" is that we already have hundreds of examples of places where biological materials find an amazing balance within whatever energy/cost/resource-availability envelope they were evolved in -- but where artificial materials (perhaps outside that energy/resource envelope) have proven to be hugely superior. I'm just hypothesizing that there's no reason to believe that biological computation will prove to be the exception.
