With "getting the hell out of here" do you mean humanity in general or you personally. If you personally: Do you really think public spacetravel will advance that much in our lifetimes?
Personally I hope so, but I also doubt it will happen.
I expect it to advance far enough that I could get off of earth personally. However the competition for free (read government funded positions) will be fierce: I'm more likely to buy the winning lottery ticket 10 times in a row. Multi-billionaires will probably be able to buy a trip.
In all likelihood, you'd be leaving this nice, hospitable planet with flora and fauna for an oversized dusty rock.
Nevermind rocks, I would be glad to just even drift in space.
