Writing anyone or any organisation a blank cheque is problematic. Even if they are perfection personified now, will they be in the future? Will it be run by none of the same people? Will they have an entirely different agenda to the one you agree with?

If you can't know these things with sufficient certainty, definitely pick your license. Then only change it deliberately for your own purposes with your own goals and ideals driving it.

Devils advocate: maybe gpl will never have a later version you could possibly disagree with as it's too important to too many people just like you.
