Electing a convicted felon President of the United States.

US conservatives calling Russia the good guys and electing a convicted felon as president.

My math teacher: "You can't walk around with a calculator in your pocket!"

Well well well, look at me NOW, Mr. York!

Satellite navigation. In my early childhood we sometimes played a street racing video game that had an arrow pointing the direction on the screen. My mom would remark that she wished she had such an arrow when she drove a car IRL, by now she definitely got that wish.

Burning a CD while using your computer for something else in the mean time.

I was laughed at on the playground when I got the idea for wireless charging back in the 90s.

Phones doing a good chunk of what computers can

Telling the "computer" to do a thing and it just does. AI has it's upsides and saves me so much time and energy

Directly measuring gravity waves, the first measurement using LIGO was back in 2016 and they've observed almost a hundred so far. The observations are being used to create newer generations of gravity wave detectors.

Being single

I don't know if people were really talking much about this kinda stuff back then, but a PC like device that wasn't a laptop that allowed you to play full-on PC titles at home, either hooked to a TV or on its own, or on the move. Especially a device that also allows you to do normal computer things outside of playing games.

Again, not including laptop since I personally don't know any people who actually used their laptops for playing games while in a moving vehicle. There probably are plenty of people who did it or do it, but I don't know any.

A battery powered table saw.

Absolutely not a thing in the 1980's, in stock now at your local Lowe's.

Owning my own home. Most of us are just going to be renting for the rest of our lives.

A computer program winning a Go tournament.

In chess, human grandmasters routinely beat the best computers, but changing that was simply a matter of faster processors and larger memory, problems solvable by the application of sufficient quantities of money. In principle the game was already solved, and within a few decades, would be solved in practice as well.

Go was considered a much harder problem. Programs of similar complexity to a decent chess program couldn't even look at a finished game between go pros and reliably say who won, let alone get there itself. Well, guess what?

Child me is just dying to have the dancing and gaming skills I have!

Self driving cars.

We are on the early stages currently; ignore what Tesla/musk says; in 10 - 20 years full level 5 autonomy will be common place.

In the 80's the Cray 1 supercomputer was made, now I have so much more computer power in my pocket its frankly ridiculous. And it's runs on milliwatts rather than kilowatts.

WW3

I've realised, over time, that we got to be species number 1 through near statistically impossible odds that is only achievable by being the most brutally effective in the game of evolution.

And millions of years of nature doesn't just go away when you're declared the winner. It is in our nature to dominate through all means possible, else we wouldn't be here. It's not so much that we want war, we need it; our nature is founded on it. When there is nothing left on the planet to defeat, we turn on ourselves to scratch the itch.

The catch is the other half of our nature is focused on domination of the species. We protect each other for the greater good as much as we kill for the greater good. That's our human nature; that's how we got here. So after a war we feel awful and promise to never do it again, but then the itch of being number 1 reappears and there's nothing else to scratch it with because we conquered everything else.

Our known history affirms that the end-game of evolution is a never ending cycle of masturbating to awful shit, feeling ashamed, and just doing it again once the shame is overridden by the urge. "Never again" we say, every fucking time.

Edit: That's why I also love the self-proclaimed "lefties" camp always misappropriating the philosophical Paradox of Tolerance on here—like it's not misappropriately used by the other camps. Ironically all just proving the paradox true. Camp vs camp. Tribe vs tribe. The itches and scratches, Oblivious to human nature doing as it does best. To progress is to win by all means possible. This is our way.

Edit Edit: And no I'm not picking on you kids specifically. Look at Tall Poppy Syndrome, Soapboxes, why communism never works, why capitalism never works; all the other ideologies we think up to break the cycle and try fast forward our evolution in vain. They all end with with someone or something taking power for a brief moment, before they're targetted to be cut down by the nature of others trying to instill their idea, how they want it, how they insist all others will want and should have it. Power.
