Personally, I don't think we will see days like that again . . . perhaps people are more cynical, perhaps it is just that no matter what the next horizon it is, technology will play a greater and greater role, and no matter how much intelligence is required to create it, or courage required to execute it, the technology itself will assume the starring role.
Also the realms of the barely possible are a lot less graspable by the general populace. A lot of people understand going faster, but calculating the correct insertion path for a planet to planet hop, no matter how technically demanding it may be, is just not as intuitive.
