It's not in your "self-interest", the way you mean it, to review your ideas and believes from when you were younger and realize that with your extra experience you see things differently now.

And just to be 100% clear, I am all for having younger people in critical positions and don't try to argue that one is better than the other.

My reply was on how age matters. Don't know why you try to twist it to a generational flame-war.
