You're one of today's lucky 10,000.

The thing to keep in mind is that computers originated as very experimental calculating machines for the military about twenty five years earlier. It would take years for people to imagine the true potential of these machine. The successive developments were not simply a matter of waiting until the underlying technology was good enough to implement preexisting ideas.

To put it in concrete terms: the concept of programming languages would have to wait until the development of the concept of stored program computers, since the notion of a programming language doesn't have much meaning in the world of plugboards (literally wiring subsystems together to tell the computer what to do). More relevant: the notion of interactive user interfaces would have been inconceivable when the sole means of interacting with a computer was via a teletype. Even once graphical displays were introduced, it would take time to go from simply representing something visually to conceiving of how the technology could facilitate HCI.

Even then my examples are highly simplified. We like to view the history of computers as a mostly linear progression. It wasn't. There were many twists and turns and abandoned paths as we learned how to make useful machines. (For fun, try researching computer memories.) A lot of the early work in computers was presented in demos that reflected the figuring out of things. While those demos may not appear as fun and the scene wasn't as culturally cohesive as the modern idea of the demoscene, the underlying spirit seems to be quite similar.
