Moore s curse technical progress is too optimistic

In 1965, this year the number of components on a chip has doubled, Gordon Moore predicted "in the short term, such rates will continue." In 1975, he modified the double time to two years later determined to be about 18 months per year to grow at a rate of 46%. This is Moore's law.

Components has become increasingly small and dense, cheap, which not only improves the performance of the products and equipment, reducing production costs, especially computers, digital cameras are light emitting diodes and photovoltaic cells. Result is to electronics, lighting and optoelectronics industry has brought change.

But revolution always has two sides: both good wishes but also difficult to break the curse. We are convinced that progress will soon have none of the technology of driving electric cars, Hypersonic, personalized cancer treatment, heart and kidney of real-time 3D printing. Even if we were told, we are preparing for the shift from fossil fuels to renewable energy in the world.

Transistor densities double time on scientific and technological progress have no significance. Depends on a lot of improve the slow process of modern life, such as food and energy production, and transport. If you look at these numbers, you will understand the development of society would not be so quick.

As the United States main crops of corn, starting in 1950 with an annual output growth of 2%.

In 20th century, after the thermal power instead of steam turbines, power generation efficiency about 1.5% a year. 1900 steam turbo-generator contrast with the 2000 combined cycle power plant, found that the average annual growth rate was 1.8%.

In all relevant sectors in power conversion, and lighting to make the greatest impression, but from 1881 until 2014 indoor lighting light efficiency (lumens per watt) annual growth of only 2.6%, outdoors was somewhat higher, and only 3.1%.

Intercontinental travel speed from 1900 ballooned to 35 km per hour in 1958 to 885 km/h (Boeing 707), with an average annual growth rate of 5.6%. But the speed is kept constant, just faster than the 707 from the cruising speed of a Boeing 787 also limited.

Between the 1973 to 2014, United States new passenger car fuel efficiency only 2.5% a year, miles-per-gallon increase from 13.5 km up to 37 km (fuel consumption increased from 17.4 per cent to 6.4 liters per hundred kilometers).

Human civilisation's most important steel energy costs (coal, natural gas and electricity) in the period from 1950 to 2010 from about 50 joules per metric ton to less than 20 joules, annual rate of approximately 1.7%.

Energy, materials and transport infrastructure to build the modern civilization, and their development has steadily increased, but the speed is very slow. Annual growth rates are in the 1.5% to 3%, and costs decreased. World outside of microchips, Moore's law no longer applies, and their development rates by an order of magnitude lower.

Tesla Model s-P85D Prada iPhone 5S case

P85D Tesla MODEL s is Tesla sells cars in the fastest and most expensive, in terms of appearance and the remaining few models did not much change, the main change is to drive and battery capacity. MODEL s-P85D, 691 peak horsepower BHP, four wheel drive, 0-96 km/h in 3.2 seconds.
