Was too much hype and expectation put on the year 2000 by those living decades ago?

Does it seem to you that pass generations or those back in the 50s and such put way more belief in the year 2000 than what was actually possible or happened? Watching old science fiction and episodes of the Twilight Zone it seems people thought by the time we arrived at the year 2000 there would be far more technical advances then there actually was. Taking a look at the movie 2001 A Space Odyssey it believed space travel was going to be much more than it was. I remember hearing that in 2001 we would have flying cars as a staple of transportation; we don’t. The way they were off about how advanced the year 2000 was, will we be off that much about what will be in the year 2050?
