On Jan. 1, nothing special will happen. Nothing involving computers, anyway. Predictions of Y2K chaos will be disproved. Why?

First, as the 10-Qs and 10-Ks of corporate America confirm, aggregate spending to head off Y2K risks has consumed billions of dollars. True, some of this money has gone for purposes other than actual computer code revision or replacement, such as canvassing business partners on their readiness (which logically, if not in practice, leads to asking business partners about their business partners, and so on). But the upshot is that most companies have already attacked even small Y2K code issues, sometimes with large armies.
