Anyone else feel this way? Think of all the greatest inventions in the world. Any of them in the past 2 decades?
Some inventions may have been improved in the past 2 decades, but very few are actually new concepts. We haven't really invented much new technology or had many scientific breakthroughs, but rather just iterated on existing concepts and made them better (which is great for our daily lives, but not for having flying cars by 2062). Think of all the shows/movies that predicted what we would have by the early 2000's and how far off they were.
The most impressive technological breakthroughs that have come from the past two decades has exclusively been hardware continuously getting smaller and faster and even that is going to quickly hit a limit, you can only make transistors so small (silicon's atomic size is 0.2 nm and we are already at 5 nm). So there's a definable limit to how good hardware can get.
Smartphones? Essentially just a small computer. Doesn't take a genius to say that someone might want to make a computer that would fit in their pocket, really it was only hardware improvements that made it possible, but again that is reaching it's limits.
You might say AI. The majority of AI concepts are from the 70's or older. AI is still very unsophisticated and only applicable to defined tasks. Just because it can simulate some human behaviour (speech being the main one), doesn't mean we are anywhere near any kind of singularity. Anyone who hypes up the singularity is spreading misinformation. I have both studied and worked in AI and I can tell you it will probably not happen, ever.
The only thing with real potential (but a lot of drawbacks as well) is quantum computing, but that isn't a new concept this side of the millenium.
We are running out of ways to leverage science to create new technologies. I believe in 60 years we will not experience anywhere near the same technological shock and awe that our grandparents experienced. It is especially disheartening considering the ability to communicate and share knowledge on the Internet has greatly improved, yet I have not seen the expected returns.
