Moore’s Law has been around since 1965 when Intel co-founder Gordon E. Moore described it in a paper. Since that day, the law has been in full effect, and the number of transistors placed inexpensively on an integrated circuit has roughly doubled every two years. It’s also a commonly held belief that chip performance doubles every 18 months.

But Moore’s Law won’t be true forever, and in the video above theoretical physicist Michio Kaku explains how it will collapse. And that collapse isn’t going to happen in some distant future, it is going to happen within the next decade.

The problem is one of finding a replacement for silicon coupled with the exponential nature of Moore’s Law. Quite simply, computing power cannot go on doubling every two years indefinitely.

The other issue is we are about to reach the limits of silicon. According to Kaku, once we get done to 5nm processes for chip production, silicon is finished. Any smaller and processors will just overheat.
