"We provide the data mankind needs to move out into space"
Mankind needs a little more than a nice destination robotic spacecraft can reach in a couple million years in order to move out into space.
Data is the first step because we need to know which direction to head. He never said the data would get us there.
The direction is somewhat less than relevant until we develop technologies that can take us (or instruments) there in less than the time it took us to evolve from monkeys.
I can't really argue with that, but sometimes having a specific destination in mind helps you get there faster.
It's depressing, I know. Having so many nice places and no starship Enterprise to take us there is no fun at all.
