No disagreement. But you don't have to use live cells to build a computational network. As to imprecise, with scaling down geometry and ramping up switching speed digital is no longer well-defined. With many small switches you're also getting reliability problems, so noise begins to creep in at the hardware layer. > Fast serial calculation.

There's also some question for what you need very high precision. Cryptography is a candidate, another one is physical modelling doing it like a mathematician. I think there is a very distinct bias, almost an agnosia if you want to do it not like a mathematician. > of operations and instant rewiring of data structures. You can't actually rewire the circuit, so you have to switch state which reprsents the circuit. It's easier if you embrace the model of dynamically traced out circuitry in a computational substrate. Very few things are instant in a current memory-bottlenecked digital computers. If you want to widen that bottleneck, you first get a massively parallel box, and eventually a cellular/mosaic architecture of simple computational elements. > If computational resources, > >which architecture? > > I don't understand the question, please clarify? If you want to build a robot capable of playing tennis in a heavy hail, how would you do it? -- Eugen* Leitl <a href="http://leitl.org";>leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE ------- To unsubscribe, change your address, or temporarily deactivate your subscription, please go to http://v2.listbox.com/member/[EMAIL PROTECTED]
