Moore's law 2015 that the pace of advancement has slowed, starting at the 22 nm feature width around 2012, and continuing at 14 nm. Brian Krzanich, the former CEO of Intel, announced, "Our cadence today is closer to two and a half years than two." Intel is expected to reach the 10 nm node in 2018, a three-year cadence. Intel also stated in 2017 that hyperscaling would be able to continue the trend of Moore's law and offset the increased cadence by aggressively scaling beyond the typical doubling of transistors. Krzanich cited Moore's 1975 revision as a precedent for the current deceleration,
Doubling time in five years, and an Egyptian proverb of the time was "If wealth is placed where it bears interest, it comes back to you redoubled." Examining the doubling time can give a more intuitive sense of the long-term impact of growth than simply viewing the percentage growth rate For a constant growth rate of "r%", the formula for the doubling time "T" is given by Some doubling times calculated with this formula are shown in this table. Simple doubling time formula: For example, with an annual growth rate of 4.8% the doubling time is 14.78 years, and a doubling time
