The Day We Could Have Stopped It! 

The Day We Could Have Stopped It! —

Experts are warning AI could lead to human extinction. Are we taking it seriously enough?

On May 31st 2023 we could have stopped it. We knew we could have stopped it; but, we didn’t.

And, at some point “Skynet” will become “self aware”.

And while we’re at it, if we ever find any extraterrestrial life forms, we shouldn’t bring it onto a ship; or bring it to planet earth.

I’ve seen the movies. These things never end well.

Wednesday May 31st 2023: The Day We Could Have Stopped It!” — scientist are warning that proposed Artificial Intelligence technology could cause the extinction of the human race.

And yet we persist in its development.

Didn’t anyone see the movie?

Ginger: "it's my new tattoo"
Cookie: "that's the best job stopper i've ever seen!"
