Why Old Technologies Are Still Kicking
In 1991, Stewart Alsop, the editor of InfoWorld and a thoughtful observer of industry trends, predicted that the last mainframe computer would be unplugged by 1996. Last month, IBM introduced the latest version of its mainframe, the aged yet remarkably resilient warhorse of computing. The mainframe stands as a telling case in the larger story of survivor technologies and markets. The demise of the old technology is confidently predicted, and indeed it may lose ground to the insurgent, as mainframes did to the personal computer. But the old technology or business often finds a sustainable, profitable life. Television, for example, was supposed to kill radio, and movies, for that matter. Cars, trucks and planes spelled the death of railways. A current death-knell forecast is that the Web will kill print media.
