Good Riddance, Win 98
Good Riddance, Win 98
People in technology industries talk about exponential growth the way teenagers talk about sex. Everyone pretends to be having it, everyone wishes they knew how to get it and none of them fully understands the implications.
The result, when either process does take place, is that bad decisions at the beginning are drastically magnified along the way.
What got me thinking about thisabout exponential growth, I meanwas this weeks termination of all sales of several long-lived Microsoft products, including Windows 98. Whenever a platform product gets euthanized, I get angry mail from eWEEK readers who depend on third-party software or specialized devices that may be orphaned by the products demise. Overall, though, Im relieved.
Lets be sure were using the same word to mean the same thing. "Exponential" does not mean "fast." A quantity has exponential growth, over time, if the amount of growth from one moment to the next is in proportion to the amount itself.
If something grows at 8 percent per year, for example, then in year 0, it could grow from 100 to 108; in year 1, from 108 to 116.64. Over 10 years, simple growth of 8 units per year gets you from 100 to 180; exponential growth of 8 percent per year gets you from 100 to 216.
The difference is vastly greater when we deal with double digits. If we start at 100 and grow by 35 units per year, in 10 years were at 450; if we grow by 35 percent per year, in 10 years were at more than 2,000. But now we come to the implication that constantly seems to escape us, only to be painfully rediscovered again and again.
If we have 100 initial customers for a product, and 250 customers after three years on the marketa comfortable growth rate of just over 35 percent per yearwe can hope to have more than 2,000 customers at the beginning of year 10, of whom 1,750 will come to us during year 3 through year 9. Seven-eighths of our customers, at that point, will be people that we attracted after three years of learning at the expense of our products early adopters. For how long, we must ask, are we obligated to keep on making the distinctive traditional mistakes that attracted the customers who got us off the ground?
To put it another way, whose needs should an IT vendor try harder to meet? The one in eight customers who liked what was first delivered, enough to tolerate its grave limits and weaknesses? Or the seven out of eight who required something better and who came to that vendor only when that became available? And who really do hope, moreover, that their IT sources will constantly do betterand who will otherwise move on to someone less encumbered by the past?
Loyalty to a products first users stems from laudable principles, but its not without costs. My favorite example is the "make" utility program, used by software developers to automate the rebuilding of applications with many components. The "make" program does the almost unthinkable: It treats the "tab" character as a distinctive symbol, instead of being merely one of many varieties of "white space." Complications ensue when other text-processing software ignores the distinction.
The explanation, admits the utilitys original author, is that "the pattern newline-tab worked ... and a few weeks later, I had a user population of about a dozen, and I didnt want to screw up my embedded base. The rest, sadly, is history."

Architect Frank Lloyd Wright once famously said that "a doctor can bury his mistakes, but an architect can only advise his clients to plant vines." Windows 98 planted vines to obscure the awkward lines of a graphical environment grafted onto a crude DOS foundation. Its time to bury it.
Windows 98 has more than a dozen users, to be sure, but it also does some dreadfully stupid things with memory and task management that we do well to purge from the software gene pool. The reliability and security of the platforms that we offer to future users depend on deep-sixing dead tech.
