The birth of Cylons. The memristor is the best synthetic neuron yet. http://physicsworld.com/cws/article/news/36497

This could clearly be a total game changer. The problem I see is that the paradigm shift is so huge that the current generation of practitioners (that's us, guys) will simply not be able to re-program our brains to usefully accommodate the new way of doing things. It brings to mind all the fuss around multi-core. By comparison that is a a minor shift, and yet everyone is frantically trying to find a way to cast multicore into an emulation of the familiar paradigm. Translation: To invent a C compiler for multicore processors that hides the profound difference in the underlying computing technology. I can just see, 20 years from now, huge protracted debates about, and failed commercial attempts to make, a C compiler that targets a memristor architecture that is totally different to the simple 100 core micros we are (by then) all using. No, IMHO what will be needed is a whole new generation of practitioners who have been trained, without having their brains polluted by "harvard" thinking, to work with the new architure. In particular the C language must go, as it should have years ago. David Stonier-Gibson http://splatco.com

What Stan Williams implies is that memristors will allow computers to be built which do not follow the traditional Von Neumann architecture which requires a CPU and stored program/data. With a memristor computer, the stored program and data is also the logic circuit. I don't see why it cannot happen. The brain is one of the most efficient computers and it doesn't follow the Von Neuman Architecture. Much of the research into memristor computing is precisely premised on computing that tries to mimic the brain. Obviously the Von Neumann paradigm will not work for a neural-synapse network based computer and new paradigms for computing - perhaps based on pattern detection and self learning will have to be developed.

Just as sensible to ask: "Will memistor CPU's obviate the need for memory?"

Darn typos. s/will replace logic/will replace cpus/ Sorry.

Ugh. "End of the CPU". What a bad title. Really this is interesting technology but the title of this article is a misnomer. The thesis that these new devices will replace logic makes as much sense as moving from software/firmware to discrete logic for all devices. It isn't going to happen for all the well known reasons. Yes, the devices are interesting. No they will not replaces CPUs. I feel like I've just been sucked to read this through a phishing expedition.
