To Keep Innovating, We Need to Rethink the CPU



And even beyond the preservation of Moore's Law or market relevance, the need for companies pushing CPU design forward is important for the future of science. Take for example, this New Yorker piece on quantum computing and the leading mind behind it, David Deutsch. It's big idea is that if we build a working quantum computer, it could theoretically process more numbers than there are believed particles in the universe.

What's that good for? It could prime factorize absurdly large numbers in a matter of seconds. And it could prove the validity the Many Worlds Interpretation. The theory essentially supposes that there is a different universe for every possible permutation of anything in the universe. One scientist, Peter Shor, developed an algorithm for quantum computers that would potentially support this theory, if we ever had a quantum computer powerful enough to run it on.
