Is Technology A Zero-Sum Game?

In last week?s Get Rich or Die Trying article, I mentioned that ?tech is a zero-sum, winner takes all game?.� A reader objected, arguing: ?I think that may be an inappropriate use of the term ?zero-sum? - one company?s increase in profits (or revenue) does not mean a competitor must see declining profits (or revenue)?. History suggests that Jack Welch?s philosophy that "a company should be #1 or #2 in a particular industry or else leave it completely" is even more applicable to the tech industry, where the top player can build a sustainable and ever-growing business but everyone else is practically better off getting out.
