Quoted from John Allman:
Brains exist because the distribution of resources necessary for survival and the hazards that threaten survival vary in space and time.
Quoted from John Von Neumann:
In mathematics, you don’t understand things. You just get used to them.
The issue of whether or not the computer and the human brain are at some level equivalent remains controversial today… Computers are not word processors. It is true that a computer and a word processor exist at different conceptual levels, but a computer can become a word processor if it is running word processing software and not otherwise.
Similarly, a computer can become a brain if it is running brain software. That is what researchers including myself are attempting to do.
The question, then, is whether or not we are can find an algorithm that would turn a computer into an entity that is equivalent to a human brain.
There is actually one genuine forerunner to Von Neumann’s concept, and it comes from a full century earlier!
English mathematician and inventor Charles Babbage’s (1791 – 1871) Analytical Engine, which he first described in 1837, did incorporate von Neumann’s ideas and featured a stored program via punched cards borrowed from the Jacquard loom.
Von Neumann applied the concept of the universality of computation to conclude that even though the architecture and building blocks appear to be radically different between brain and computer, we can nonetheless conclude that a von Neumann machine can simulate the processing in a brain. The converse does not hold.
