Photonic computing processes information using light, whilst neuromorphic computing attempts to emulate the human brain. Bring the two together, and we may have the perfect platform for next generation AI, as this video explores.

Back in the late 70’s, when I studied electronics at University, we were imagining neural networks based on a self modifying, distributed type structure using a hybrid of analog and digital techniques. The technology didn’t exist back then. Digital processing took over and got us to the point we are today and now, 40 years later, the technology may be finally catching up.

@squelchstuff 3 года назад

Brilliantly accessible coverage of the subject Christopher. Thanks also for your research sources too. Photonic Neuromorphic Computing is such a mouthful, so it's only a matter of time before the marketing bods come up with some strange acronym. PNC has a different (and depending on your proclivities/recidivism) meaning in the UK :)

@jeraldgooch6438 3 года назад

Christopher, 1. Please excuse the tardiness of this note. I watched the video on Sunday, but got waylaid by the world. Namely Mother's Day 2. I can see why you would be a good and effective lecturer at university. You took a very complex topic and condensed it down to a number of relatively easily digestible bits and presented them effectively. In other words, you effectively dumbed down a complex topic without talking down to me. That is hard to do. 3. So, it appears computers are making advances in three areas a. semiconductors go for ever smaller trace sizes and compressing more transistors into smaller and smaller spaces b. quantum computing is still being researched and on sees bits and pieces about advances in this area and some semi-practical devices c and no photonic computers d. (no doubt there is still someone out there still touting fluidics and the cure for what ails you) 4. One wonders what programming languages (and operating systems) will look like for photonic and quantum computing devices will look like? Will the interfaces still be electronic with visual and touch devices or will there be more direct interface with the brain? 5. When will we be seeing the SBC version of a photonic computing device from someone like Raspberry Pi? 😊

I remember a movie about Time Travel and a photonic intelligence. "Time travel. Practical application." On that note, there's also a game featuring a von Neumann probe. Grey Goo, a fairly decent real-time strategy game.

@AlRoderick 3 года назад

The von Neumann probe is a different concept then the von Neumann architecture, invented by the same guy (he was a prolific futurist). He posited the idea of self-replicating machinery, macro scale space probes that would go to other star systems, build copies of themselves, and send the copies forward to still more star systems. This process would repeat until you visited every single star system in the galaxy. Other later thinkers applied that same concept to nano scale machinery, which is where we get the grey goo idea that's the source of that game's name. Ironically a nanomachine would probably not use the von Neumann architecture.

So I’m looking forward to seeing what comes along. I’m really excited about using entanglement in communication/ information tech. I kind of wonder how far we will go.. I guess only time will tell.

Back in the early 80's, IBM patented a process that used red and green lasers, to read and write a crystal made of the same molecule inside your eyes. When the red laser hit this molecule, it turned to "L" shape. When hit with the green laser, it would turn to an "I" shape and straighten out. Or something like that. They said, they can fit 10 libraries of congress on a crystal the size of a sugar cube! They were going to make solid state optical drives that had fast read and write speeds (in nano seconds). I never heard anything after that. Anyone else remembers this?
