It means that e.g. processing speed or memory capacity of conventional computers is improving at roughly exponential rates.  This was true for the last half a century and is believed to continue until at least 2015 or 2020. But as Gordon Moor, Intel co-founder, admitted in 2005, it cannot continue forever. As we are approaching atomic scales, we are approaching the fundamental barrier where quantum mechanics is coming into play (e.g. by quantum tunneling). Some people believe that a new type of technology (e.g. quantum computers [3]) will replace current integrated-circuit technology and Moore\u2019s law will hold true long after 2020, but it remains an open question.<\/p>\n<p>References:<\/p>\n<p>[1] <a href=\"http:\/\/www.sciencemag.org\/content\/309\/5731\/96.full\">http:\/\/www.sciencemag.org\/content\/309\/5731\/96.full<\/a><\/p>\n<p>[2] <a href=\"http:\/\/en.wikipedia.org\/wiki\/Moore's_law\">http:\/\/en.wikipedia.org\/wiki\/Moore&#8217;s_law<\/a><\/p>\n<p>[3] M.
