Motherland, they said the same thing about transatlantic crossing with aircraft, and if you go back further, with sailpowered ships.
Never say never... it may not be in our lifetime, but it will happen (if we don't annihilate ourselves first).
I've no doubt that eventually we'll be in space, and that there will eventually be found legitimate reasons and great benefits of us being there and exploring it more fully. I think NASA's a great program.
But I think it's ridiculous to think that private investors will be the way to get there, considering that we've already spent trillions of dollars on it with not a whole lot to show for it, other than to say we've done it, which doesn't exactly help the bottom line at all for a private investor, so there's no point in it unless he's just in it for the fame, and, let's face it, even these guys have limited funds and they're extremely few and far between.
I have no doubt that private space travel and exploitation will be there eventually, but it will be long after state programs have created the technology and infrastructure necessary to make it profitable and worthwhile. We're still far from that point.
