Moores Law.

Moore's law is an observation made by Intel co founder and Business man Gordon Moore that the number of transistors on an integrated circuit doubles every two years. In 1975 this was changed from 2 years to 18 months as more variables were taken into account such as faster transistors. Moore's is not a very useful system for describing the growth rate of technology past the 2020's as it is limited by how many transistors you can fit on an integrated circuit. As technology advances rapidly in the next few decades Moore's law won't work as it will be near impossible to predict the rate of doubling. It has been predicted that by around 2021 Moore's law will stop as the growth rate of technology advances so much that it impossible to predict even something as simple as the doubling of circuits. After Moore's law is passed Humanity will need to figure out how to deal with the problems of making faster computers. One possible scenario is that all the Transistors will be replaced with nano bots that allow information to be transmitted faster than ever before. These nano bots could be used to accomplish almost any task from bringing back the dead to building even more nano bots to accomplish even greater tasks. The first one of bringing the dead back to life could work by uploading an individuals computer into the Nanobots who would in turn build a body for the deceased person. The ultimate limits too how small technology can get are unknown but with our current knowledge of physics it seems that the Planck Length is the limit. The Planck Length is the smallest measurable unit of distance found in Quantum physics and string theory. It is possible that there are things smaller than the Planck length but these purely hypothetical objects would not act according to the known laws of physics. Sub Planck scale engineering won't happen till around 1000,000-10,000,000 ad when Humanity has the power to warp reality on a universal scale.
