Security prices have two basic outcomes: "up" and "down." Usually they fluctuate, so almost any call will "eventually" be proven correct. Sporting events are also mostly binary outcomes, so "the Cubs will reach the World Series" will probably be right if given 200 years. But with technology predictions, there's an almost infinite set of outcomes, so being right in direction but not timing is significant. For instance, someone who says "Little Rock, Arkansas will win the Super Bowl within 5 years" will look pretty smart even if it takes 6 years for Little Rock to (very unexpectedly) get an NFL franchise and 9 years to reach the Super Bowl. Granted, technology predictors can use also use some tricks to narrow the possibility space in their favor.
