Moore's Law is mention anytime there's an advancement in processing speeds, and that may keep happening for another 75 years. Physicists are speculating that, assuming Moore was right, we'll max out on processing speed at that point.
If you're not familiar with Moore's Law, it's the idea that computing speed will double roughly every two years due to factors such as smaller and smaller transistors being used in chips. That's great, but like with nearly anything else, there has to be a limit to the process:
If components are to continue shrinking, physicists must eventually code bits of information onto ever smaller particles. Smaller means faster in the microelectronic world, but physicists Lev Levitin and Tommaso Toffoli at Boston University in Massachusetts, have slapped a speed limit on computing, no matter how small the components get.
Physicists estimate that we won't reach this limit until the 75 year mark from now. But others have suggested that it's actually far sooner, only 20 years away. Heck, I've heard five years at some point. Whatever the time frame is, I'm curious about is what the actual speed limit will wind up being. (Mind you, I'd love to see it hit during my lifetime, too. Just to know for sure.) [Live Science]
