Uncharted Territory

Moore’s Law, the theory that the speed and power of microchips will double every two years, is, as Andrew McAfee and Erik Brynjolfsson posit in their book, “The Second Machine Age,” so relentlessly increasing the power of software, computers and robots that they’re now replacing many more traditional white- and blue-collar jobs, while spinning off new ones — all of which require more skills.


The chips are down for Moore’s law
The semiconductor industry will soon abandon its pursuit of Moore's law. Now things could get a lot more interesting.

Next month, the worldwide semiconductor industry will formally acknowledge what has become increasingly obvious to everyone involved: Moore's law, the principle that has powered the information-technology revolution since the 1960s, is nearing its end.

A rule of thumb that has come to dominate computing, Moore's law states that the number of transistors on a microprocessor chip will double every two years or so — which has generally meant that the chip's performance will, too. The exponential improvement that the law describes transformed the first crude home computers of the 1970s into the sophisticated machines of the 1980s and 1990s, and from there gave rise to high-speed Internet, smartphones and the wired-up cars, refrigerators and thermostats that are becoming prevalent today.

None of this was inevitable: chipmakers deliberately chose to stay on the Moore's law track. At every stage, software developers came up with applications that strained the capabilities of existing chips; consumers asked more of their devices; and manufacturers rushed to meet that demand with next-generation chips. Since the 1990s, in fact, the semiconductor industry has released a research road map every two years to coordinate what its hundreds of manufacturers and suppliers are doing to stay in step with the law — a strategy sometimes called More Moore. It has been largely thanks to this road map that computers have followed the law's exponential demands.


Heat death
The first stumbling block was not unexpected. Gargini and others had warned about it as far back as 1989. But it hit hard nonetheless: things got too small.
“It used to be that whenever we would scale to smaller feature size, good things happened automatically,” says Bill Bottoms, president of Third Millennium Test Solutions, an equipment manufacturer in Santa Clara. “The chips would go faster and consume less power.”


Going mobile
The second stumbling block for Moore's law was more of a surprise, but unfolded at roughly the same time as the first: computing went mobile.
Twenty-five years ago, computing was defined by the needs of desktop and laptop machines; supercomputers and data centres used essentially the same microprocessors, just packed together in much greater numbers. Not any more. Today, computing is increasingly defined by what high-end smartphones and tablets do — not to mention by smart watches and other wearables, as well as by the exploding number of smart devices in everything from bridges to the human body. And these mobile devices have priorities very different from those of their more sedentary cousins.


Cramming More Components onto Integrated Circuits

まあ自らMoore’s Lawと命名するわけではないのでここにはそんな言葉は書いてありませんが。。。(苦笑)
