You know, the sad thing is that a lot of people feel that way. They never saw the real impact on technology, science, education, and most importantly on the way the country felt as a whole. All this was going on during Viet Nam and offered a bright hope to those struggling through the war. During this time, 2001 A Space Odyssey came out as well. Think about it, they created the movie before we ever saw the earth from out of orbit! Uncanny to the point I felt is was a contract with us on what was to come. So, here we are in 2008 still unable to get out of earth orbit for about 40 years...we made it from zero to the moon in less than 10!
If you want to read a fascinating prsentation on why people lost interest, take a look at the Gen Y presentation given to NASA management. It is excellent and I have been using it extensively in my company with a lot of impact.
I'm still dreaming and hoping but at this point, I realize I will not live to the see the things I felt 2001 promised me. It is sad and has actually made me move more towards sci fi modeling. I can control what happens there
