The 50-year Inflection Point

A strategic inflection point is a time in the life of business when its fundamentals are about to change. That change can mean an opportunity to rise to new heights. But it may just as likely signal the beginning of the end.

—Andrew S. Grove, Only the Paranoid Survive (1988)

In the late 1960s Intel sniffed the winds of change and made a dramatic decision to build microprocessors instead of random access memory, RAM. Former Intel CEO Andy Grove describes this abrupt change in Intel’s strategy as an inflection point. As we know from mathematics, the coordinates of an inflection point are where a curve changes direction—typically from up to down or the reverse. In the case of young Intel, the RAM business was no longer profitable, and yet, the profitability of microprocessor chips was totally unknown. It was a choice between dying along with the RAM market or possibly dying with an unproven product in a non-existent market. We now know Grove was right, but he could have been wrong. Such is the life of an entrepreneur.

It has been 50 years since Intel’s inflection point was recognized and then mostly forgotten. But the company and the industry it grew up with is facing another inflection point—the demise of Dennard scaling—the 1974 rule that the power consumption of CMOS chips remains constant as transistors are scaled down in size.

The Elevator—Extraordinary Ordinary Things

There’s a widely accepted principle about technology adoption. When a new technology is introduced, people are aware of it and   learn how to use it. After a while, people come to embody the practices of using it well and are no longer aware of it. It is just part of our world. We no longer notice how we ever lived without it. Some say this principle is characteristic of the computer age. However, this did not originate with computers. It has always been the case with revolutions in daily life. Those who see the revolution taking place are unlikely ever to forget it. Those who see only the effects of the revolution often don’t fully recognize and appreciate it. I call examples of this phenomenon “extraordinary ordinary things.” For me, the most undervalued extraordinary ordinary thing is the elevator.

In Praise of Spaghetti Code

Spaghetti code is not getting any respect. Software experts denigrate it; coding classes avoid it like the plague; and when students go out into the world, they spend inordinate amounts of time trying to follow their mentors’ instructions. This unalloyed disparagement of spaghetti code is unfortunate, because we owe so much to it. Continue reading In Praise of Spaghetti Code

Is Computing in Reverse the Next Big Thing?

As Moore’s Law runs out of steam, and fabrication of Boolean circuits on silicon appears to be reaching its limits, some computer scientists and physicists are looking beyond the limits of current computing to “reversible computing.” That is, instead of one-way circuits that produce a deterministic output from given inputs, reversible computing works both ways: Inputs can be obtained from outputs by running the circuits in reverse. Generally speaking, computation runs in one direction, producing outputs from inputs, without the ability to run backwards and compute inputs from outputs.
