That's what's beautiful, is like, the pace of technological change is really going exponential again, just kind of like it was during Apollo. So we're back onto that really rapid fast track. We kind of fell off of that for a little while. And the nice thing about people ask me, like, what's the biggest difference between working at SpaceX and working at NASA? And I would say it's decision speed, because we'll make up our mind quickly. Now, the reason we can do that is we got a tremendous amount of agility, because sometimes when you make up your mind quickly, you make the wrong decision. Right?
