A-Clue.Com will cease in its present form at the end of the year. It will be moving here, becoming a regular weekly feature of the DanaBlankenhorn.Com blog.
To celebrate this change I have five essays on the main topics this blog has covered in its decade of e-mail existence, looking mainly at their present and future. First, last week, was e-commerce, the original beat here. Today I have an essay on Moore's Law. Next week features The World of Always-On, then we go on Political Cycles, before finishing up with a big Internet Future essay.
Enjoy.
Gordon Moore doesn't agree with me about Moore's Law.
His statement from last year, that Moore's Law is dead, was narrowly drawn and true as far as it went. Fact is the closer you bring circuit lines together, the bigger the magnetic interference when you run electricity through them. Beyond that there is a theoretical limit – when lines get within 1 nanometer of one another, they cease to be separate lines.
But the Moore's Law Process is very much alive. We see it in hard drive capacity, where disk sizes double at the same price every 18 months or so like clockwork. We see it in optical drives, where every few years features a dispute between manufacturers over technology that's 10 times better than what came before. We see it in optical cable, where the use of different colors lets makers pack ever-more bits down the same pipe. We see it in wireless, where improved digital signal processors enable a 802.11n modem to run 10 times faster than an 802.11b, on the same frequency spectrum.
We even see it at Intel, in the chip sector. The company bit the bullet on its designs two years ago, and now pushes ahead with lower-power chip technologies and multiple processors on a chip. The quad chips of today are indeed four times faster than the single processor chips of three years ago, just as Moore's Law would have predicted.
