That there is no blocker doesn't mean there is isn't one. I am as optimistic as they come, but let's look at much smaller problem: modeling an arbitrary analog

That there is no blocker doesn't mean there is isn't one. I am as optimistic as they come, but let's look at much smaller problem: modeling an arbitrary analog circuit with DSP. The Nyquist theorem implies it's impossible to model such a circuit perfectly. Is there hope for perfectly modeling a physical brain with an electrical computer?
