I think that really depends on whether the discussion is addressing the technological capability, or the desire of the general human population to get the job done.
Our technology is astounding compared to even 50 years ago, and the rate of invention and discovery continues to accelerate. While we haven't come up with a solution for launches other that liquid and chemical rocketry, that's not an inherent show stopper. We went to the moon that way, and the refinement of that craft has only increased in quality since then. In addition, the baton has been passed in many ways from NASA to independent companies who are addressing space flight from a capitalistic viewpoint - one that historically gets things done. No bucks, no Buck Rogers and so forth. I really do think we will be sneaking up on the ability quite rapidly at this point.
In regard to the general desire of the species to accomplish these tasks? Yikes! We truly, by majority, don't have the motivation required. There's a reason that necessity is the mother of invention. Those that live in parts of the world that would be considered stable and economically sound are exposed to a higher level of comfort and distraction than at any other point in history. To wit, here I am on an Internet message board discussing topics connected to a company that provides leisure and recreation. That's a bit crazy if you take the time to think about it, but I don't recommend it. Those that live in destabilized parts of the world often have more urgent necessities such as survival to worry about. Of what value is space exploration to anyone when framed in that scenario? Ultimately, in both cases, it's hard to attract or justify the needed consensus of will to move forward.
So then, technology? Check! Rapidly closing in on our goals. Our global society? Ehhh....needs some work, we'll get back to you on that one.
