Making light work of Al

摘要

Silicon has been making our computers work for almost half a century. Whether designed for graphics or number crunching, all information processing is done using a million-strong horde of tiny logic gates made from element number 14. But silicon's time may soon be up. Moore's law - the prophecy which dictates that the number of silicon transistors on microprocessors doubles every two years - is grinding to a halt because there is a limit to how many can be squeezed on a chip.
