For younger readers, this challenge will be difficult, but if you're about 25-40, this will be easier:

Think back ten years ago. What were the tech predictions at the time? Now, look around and ask yourself how many of them exist today? Very few.

Just a few examples from 3-5 years ago:

• A company was working on blood tests that would significantly lower costs and result in less blood needed. Now, we know the technology was invalid (Theranos).
• Robots have been portrayed doing amazing things five years ago, predicting what we'd have access to then. Yet, this year people freaked out about a Robot that opened a door. That's it? It's the year 2018 and we finally have a robot that opens a door?
• A wind sail technology would reshape energy. We have yet to see it applied anywhere in large amounts.

Don't get me wrong: the journalists who write about this new technology are selling us on what we want to be true. I discuss this in discovering truth - appeals to emotion are powerful. Still, most of what is asserted today about technology will not be true in the future.
