You're suffering from selection bias. The first people who found out about multimedia CD-ROMs... didn't do that well because the web killed those off after three years. The first people who invested in 3D television technology... went nowhere, no one bought them. The Internet did go places, it's true. But, the first Internet companies are mostly dead. For every success like Amazon there are 1000 dead dot-coms. Etc. Knowing about new technologies (languages, libraries, frameworks) is useful in terms of "oh I might need this tool someday" kind of way, but that's a very different goal.
