It never quite ceases to amaze me that Moore's Law continues to hold.
Moore's Law (which was first articulated in 1965 by Intel co-founder Gordon Moore) is based on an empirical observation that the number of transistors on a chip can be doubled every 24 months.
It has not been broken since 1965 and seems set to continue because Intel has just announced that it will start production this year of 45nm transistor technology, which means that Moore's Law will continue to hold for the foreseeable future.
There has been a lot of speculation in recent years that we are reaching the limits of how densely transistors can be placed on a chip due to their ever shrinking size, which is now close to the size of an individual atom, although Moore himself doesn't think this will be an issue for another decade or two.
