The Ultimate Limit of Moore's Law

BuzzSkyline writes "Physicists have found that there is an ultimate limit to the speed of calculations, regardless of any improvements in technology. According to the researchers who found the computation limit, the bound 'poses an absolute law of nature, just like the speed of light.' While many experts expect technological limits to kick in eventually, engineers always seem to find ways around such roadblocks. If the physicists are right, though, no technology could ever beat the ultimate limit they've calculated — which is about 10^16 times faster than today's fastest machines. At the current Moore's Law pace, computational speeds will hit the wall in 75 to 80 years. A paper describing the analysis, which relies on thermodynamics, quantum mechanics, and information theory, appeared in a recent issue of Physical Review Letters (abstract here)."

    I guess our kids and grandchildren have their work cut out for them.

    Don't worry, they'll be too busy paying back all the money we've borrowed over the last few decades to worry about how fast they can make their computers ;)

    Don't you worry.

    By then the dollar will have inflated and shrunk the national debt to less then the price of an once of gold.

    The real suckers are the ones buying T-bills.

    Is that eloquent enough for you, parasite?

    You asked me a question, to go out of my way to give you knowledge, to do something for you, and you did it in the most insulting way.

    I feel no need nor desire to honor your request. Go investigate the history of the integrated circuit yourself; asking other people to do it and inform you while insulting them makes YOU a parasite. And a troll.

    It's frustrating to spend years trying to combat the "arrogant, insulting scientist" stereotype, then see all my efforts negated in the span of a single slashdot post. I see now why so many people are creationists and climate-change deniers.
