Ben, The problem with this article is that it is SO vague. Saying that they are doing something in analog is just about as vague as saying that they are doing in digital.
For example, many people think that analog is necessarily "hard wired", but designs can easily incorporate memristor-based crossbar "switches" that can make them even more adaptive than present digital implementations. Also, there are circuits that are neither cleanly analog or digital, that can periodically force a capacitor to the nearest step of charge, so that capacitors can hold accurate analog values forever. Then, there is the whole area of birdirectional computing that I have posted on in the past, that offers SO much more than present unidirectional computing practices. Bidirectional computing is SO easy in analog - like it is sometimes hard to avoid, whereas it is VERY difficult in digital, e.g. the time to simulate an electric circuit in SPICE or other circuit simulator rises as the SQUARE of the size of the circuit. I think there is great promise in hybrid implementations, but so far every proposal I have seen has failed to really capitalize on the medium - what analog can do that digital can apparently NOT ever be scaled up to do. Is there any more detail about this project?

Simply institute a six hour workday. That will easily create enough new jobs to bring back full employment. ------------------------------------------- AGI Archives: https://www.listbox.com/member/archive/303/=now RSS Feed: https://www.listbox.com/member/archive/rss/303/21088071-f452e424 Modify Your Subscription: https://www.listbox.com/member/?member_id=21088071&id_secret=21088071-58d57657 Powered by Listbox: http://www.listbox.com
