We're in the '20s!

We have rockets landing on their launch towers.

We have America's Cup yachts sailing at 4x the wind speed.

We have AIs outscoring grad students on exams.

We have self-driving cars that may be better than humans.

We have solar power under 2 cents per kWh.

And we have a presidential candidate talking about getting rid of the bad genes from immigrants, and a global 20% tariff. Hello, 1920s!
