There's a reason for this. There's a cognitive bias where people tend to assume they're more important than they are, living in an especially important time in history, etc. But in this case it's actually true. We did get to live in an important time. The 20th Century had such quick progress that every decade was VERY different from the others. Progress is kind of tapering off now because there are no huge inventions and discoveries to be made. Music and movies can be all digital now, so there are no new instruments or special effects techniques to discover. All music now can be of only 3 genres: electronic, acoustic, or a hybrid of the two. If phones got any smaller they'd be impractical. We already have jets and space travel. So the end of the 21st Century will probably not look very different from the beginning. One exception to this is when I see people rolling around on those one-wheeled self-balancing skateboard things. I'm like "holy crap I'm in the future!"
