Hello everyone. We all know that conventional data computing technology is not sufficient to make complex mathematical calculations in some sense and we need to look at some other data computing technologies. I did some reading but could not deduce any answers for the following questions. Anybody interested please help. Scientists say, they need Artificial Intelligent system to make accurate judgement. So, they are shifting to Artificial Neural Networks to achieve that accuracy. It's a different thing that they found out new ways to deal with Artificial Intelligence in a conventional way to achieve this accuracy. But let's talk about Artificial Neural Network. My questions are interlinked. Question 1: Like we all know all living organisms have DNA. DNA carries information and determine the traits of species. DNA is biological, contains molecules, and there are four types of nucleotide s in DNA. And arrangement of these nucleotide vary from one living creature to another, which defines the traits of a living thing. So, in molecular computing (Molecular computers), if the scientists create a data computing processor which is not made of silicon but DNA, does it really mean that the scientists will be using biological DNA to make processors and DNA "constructed" is not going to be some sort of artifact made of electronic components? It's a silly question, but I am finding it hard to believe this. Because, if the scientists really make a processor using biological DNA how can they manage to keep the DNA alive? Will it have a survival period? Question 2:(please see the figure) On the right side of the figure. I know that there should be a system that should process all the non-linear signals/responses. I don't intend to raise any questions about the details of this system and the way it processes non-linear signals but my question 2 is to know what this Artificial Neurons in Artificial Neural Network is made out of. Because, some video on internet says "Artificial Neural Network is VLSI implementable." And a different source says that "ANNs (Artificial Neural Networks) are usually just computer programs with a network of data structures, not an actual physical network". Please note the word "usually" in the last sentence. Therefore, I want to know, is this Artificial Neural Network a hardware or software or both! Question 3: I think that Quantum computers are most powerful of all computers then followed by Atomic computers then Molecular computers then Photonic computers. Right? And the concept of data processing in Photonic computers can be used in any of the previously mentioned types of data computing technologies. Right? - The concept that I am refering to above is the way how photons are used to send data from one location to another, if the need arise. So, I can incorporate this concept in any/all of those above mentioned data computing technologies. Right? And if there is some processor which is completely made of some material that processes light signals directly that will be requiring less heat dissipation mechanism that will be well and good. I need more information on this subject. Please suggest any books, websites. Feel free to write any terminologies associated with A.I and these questions. I am going to use internet to learn. Please post concrete information and let's not make this thread look science-fictional. Your posts are valuable to me. Thank you.
