Not necessarily.
The false nine is one of two directions in which the centre-forward position seems to be heading (at the highest level – lower down, where control of possession and imagination of approach are necessarily less prioritised, the traditional virtues of being quick or big or predatory are still of value). If he is not refining himself out of existence, he is doing the exact opposite, and imposing himself as a powerful leader of the line and creator of space in the manner of Didier Drogba, Emile Heskey or even Bobby Zamora. Some, such as Dimitar Berbatov and Zlatan Ibrahimovic, combine both styles.
Either way, the situation has emerged whereby a striker's primary function is no longer to score goals, but to create the space for others to do so. Obviously it's advantageous if he can take chances, or even conjure up goals out of nothing, which is what makes Drogba and Fernando Torres so special, but increasingly goals alone are an inadequate measure by which to judge a forward. If the poacher isn't dead yet, he may well be in a decade's time.
