RISC (Reduced Instruction Set Computing) is not a new idea at all, and it already has changed everything. CISC has been dying for decades now, because it's hard to optimize very complex architectures.
It's a quote from the movie Hackers. If you haven't seen it yet, do it! Just don't hope for realism ;)
I predict that the year of desktop Linux will coincide with the death of CISC.
