you are quite wrong on that. that is where you are failing to understand, you cant get past that idea.
there is also a large difference in scale. your silicon is going to need assembly/organization on the scale of individual molecules, and there will be self assembly required as that level of organization is constantly changing.
the barrier is mechanical scale construction, as the basic unit of function,that is why silicon and code cant adapt, cant exploit hysterisis, cant alter its own structure and function at an existentially fundamental level.
you are holding the wrong end of the stick. biology is not magic, it is a product of reality.
