Wanna bet that the 2020s would be called "post-scarcity" by cavemen? You can buy food without sabertooth tigers assaulting you! If you get a cut, you probably won't die! Fire is the press of a button! We make shelter, not buy it! (and all of this was true like 150 years ago -- not sure what they would make of the internet...).

Project this forward another several thousand years and people will be laughing at us:

- You had to call up people and were limited by the speed of light?

- You didn't have teleportation?

- You lived <100 years and died due to cancer?

- You were still asking "WTF is gravity"?

- You hadn't had the +2 spacial and +1 time dimensional implants in you yet?

- You hadn't adopted the metric system yet?

And so on...
