NOTES
1. A consortium of eighteen manufacturers of cellular telephones and other portable electronic devices is developing a technology called Bluetooth, which provides wireless communications within a radius of about ten meters, at a data rate of 700 to 900 kilobits per second. Bluetooth is expected to be introduced in late 1999 and will initially have a cost of about $20 per unit. This cost is expected to decline rapidly after introduction. Bluetooth will allow personal communications and electronics devices to communicate with one another.
2. Technology such as Bluetooth (see note 1) will allow computer components such as computing units, keyboards, pointing devices, printers, etc. to communicate with one another without the use of cables.
3. Microvision of Seattle has a product called a Virtual Retina Display (VRD) that projects images directly onto the user's retinas while allowing the user to see the normal environment. The Microvision VRD is currently expensive and is sold primarily to the military for use by pilots. Microvision's CEO Richard Rutkowski projects a consumer version built on a single chip before the year 2000.
4. Projecting from the speed of personal computers, a 1998 personal computer can perform about 150 million instructions per second for about $1,000. By doubling every twelve months, we get a projection of 150 million multiplied by 211 (2,048) 5 300 billion instructions per second in 2009. Instructions are less powerful than calculations, so calculations per second will be around 100 billion. However, projecting from the speed of neural computers, a 1997 neural computer provided about 2 billion neural connection calculations per second for around $2,000, which is 1 billion calculations per $1,000. By doubling every twelve months, we get a projection of 1 billion times 212 (4,096) 5 4 trillion calculations per second in 2009. By 2009, computers will routinely combine both types of computations, so if even 25 percent of the computations are of the neural connection calculation type, the estimate of 1 trillion calculations per second for $1,000 of computing in 2009 is reasonable.
5. The most powerful supercomputers are twenty thousand times more powerful than a $1,000 personal computer. With $1,000 personal computers providing about 1 trillion calculations per second (particularly of the neural-connection type of calculation) in 2009, the more powerful supercomputers will provide about 20 million billion calculations per second, which is about equal to the estimated processing power of the human brain.
6. As of this writing, there has been much publicity surrounding the work of Dr. Judah Folkman of Children's Hospital in Boston, Massachusetts, and the effects of angiogenesis inhibitors. In particular, the combination of Endostatin and Angiostatin, bioengineered drugs that inhibit the reproduction of capillaries, has been remarkably effective in mice. Although there has been a lot of commentary pointing out that drugs that work in mice often do not work in humans, the degree to which this drug combination worked in these laboratory animals was remarkable. Drugs that work this well in mice often do work in humans.
