If nothing really disruptive happens in the mean time (major nuclear war, substantial human intelligence enhancement, human-level AI, etc.), when will Moore's law level off? The points on the graph show past data.

• Claim: The amount of computing power that can be purchased for a given amount of money has doubled roughly every eighteen months since at least 1960. On May 1st, 2008, at the Intel Developers Forum, Pat Gelsinger, the senior vice president and co-general manager of Intel's Digital Enterprise Group, predicted that this trend will continue through 2029.
  Implication: Given no major disruptions, we can expect the regular doubling in available computing hardware per dollar to continue through 2029.

• Claim: "In terms of size [of transistor] you can see that we're approaching the size of atoms which is a fundamental barrier, but it'll be two or three generations before we get that far — but that's as far out as we've ever been able to see. We have another 10 to 20 years before we reach a fundamental limit. Electronics though is a fundamental technology that's not likely to be replaced directly. There's a difference between making a small machine and connecting them by the billion. Nanotech will have an impact but it's not about replacing electronics in the foreseeable future." — Gordon Moore, co-founder of Intel, 2005
  Implication: The doubling in available computing hardware per dollar will run into fundamental limits sometime around 2015 or 2025, leveling off into an S-curve.

• Claim: Developing more and faster chips requires large consumer demand for such chips, and such demand will not be present in the future.
  Implication: Hardware availability will slowly flatten out at some demand-driven upper limit.

• Claim: "In accordance with the law of accelerating returns, paradigm shift, also called innovation, turns the S curve of any specific paradigm into a continuing exponential. A new paradigm (e.g., three-dimensional circuits) takes over when the old paradigm approaches its natural limit. This has already happened at least four times in the history of computation." — Ray Kurzweil, The Law of Accelerating Returns (2001)
  Implication: The costs of hardware will continue falling exponentially for at least a century.
