Modern-day computers are based on logic circuits using semiconductor transistors. To increase computing power, smaller transistors are required. Moore's Law states that the number of transistors that can fit on an integrated circuit should double every two years due to scaling. But as transistors reach atomic dimensions, achieving this feat is becoming increasingly difficult. Among the most significant challenges is heat dissipation from circuits created using today's standard semiconductor technology, complementary metal-oxide semiconductor (CMOS), which give off more heat as more transistors are added. This makes CMOS incapable of supporting the computers of the future. Engineers are therefore seeking alternatives to CMOS that would allow for highly efficient computer logic circuits that generate much less heat. Northwestern University researchers may have found a solution: an entirely new logic circuit family based on magnetic semiconductor devices. The advance could lead to logic circuits up to 1 million times more power-efficient than today's. Unlike traditional integrated circuits, which consist of a collection of miniature transistors operating on a single piece of semiconductor, the so-called "spin logic circuits" utilize the quantum physics phenomenon of spin, a fundamental property of the electron. "What we've developed is a device that can be configured in a logic circuit that is capable of performing all the necessary Boolean logic and can be cascaded to develop sophisticated function units," said Bruce W. Wessels, Walter P. Murphy Professor of Materials Science and Engineering, one of the paper's authors. "We are using 'spintronic' logic devices to successfully perform the same operations as a conventional CMOS circuits but with fewer devices and more computing power."

I'll agree with you that it means nothing...only because within the next 10 years, something better and implementable will be in place.
Trust me on this one.

As a futurist, yes computers and digital technology will lead to some great things. The potential is great, both for good and for abuse, unfortunately.
Civilization will go 1 of 3 ways:
1) No advance due to humans killing themselves first / losing technology / the elite refusing to let it advance.
2) The tech becomes widely available and human civilization flourishes and reaches its greatest potential yet.
3) The tech becomes available and acknowledged, but is kept in the hands of the wealthy, creating a real-life cyberpunk dystopia in the future.
Which way will it go?
