Seems like the media should at least express some curiosity about this.

AI Expert Tells Bernie: “The Humans will be Discarded”
AI Expert Tells Bernie: “The Humans will be Discarded” YouTube video by Senator Bernie Sanders

Will AI become smarter than humans?

If so, is humanity in danger?

I went to Silicon Valley to ask some of the leading AI experts that question.

Here’s what they had to say:

Senator Collins:

I'm asking you, not as your opponent, but as a Mainer and a veteran who has seen too many people die.

You can stop this war machine before it chews up any more lives.

If you still have a conscience somewhere under all that concern, we need you to find it.

Maria Goeppert Mayer depicted on a U.S. postage stamp

For #WomensHistoryMonth: Let us celebrate the life and accomplishments of Maria Goeppert Mayer (1906-1972), Ph.D. theoretical physicist and only the second woman to win the Nobel Prize in physics. She shared the 1963 prize for her work in developing the shell model of nuclear structure. 🎢⚛️🧪 1/n

All of a sudden I am seeing a lot of people attacking Graham Platner— however listen to what he is fighting for— taxing the rich and fighting for universal healthcare. I can’t think of a better platform. I’ve been waiting for a candidate to speak out about these issues coherently for decades.

Israel & Saudi Arabia pushed the U.S. to attack Iran.

Netanyahu killed 72,000 people in Gaza, mostly women & children.

Saudi Arabia is a brutal dictatorship that allows no opposition.

These are the leaders who want to bring “freedom” to Iran?

Does anyone really believe that?

This war must end. Our Senators and Congressman must not know a moment’s peace until this ends.

The morally bankrupt Trump administration has partnered with another morally bankrupt authoritarian to declare an unprovoked war on Iran, already killing scores of civilians.

We need an immediate vote from Congress on a War Powers Resolution. Then articles of impeachment.

A Tale of Two Teams—Why Trump’s Joke Wasn't Funny Locker room "jokes" contribute to a bigger problem with how women are treated.

Both U.S. Olympic hockey teams won gold. But only the men got a presidential call and celebration, while the women were met with a joke at their expense. The contrast isn’t just about sports. It’s about how respect, power, and attention are allocated in our culture.

Trump and Bondi and others in the administration want the public to believe that Christians (but only their approved kind) are persecuted in America for their beliefs (anti-abortion, anti-LGBTQ+). But they just censored James Talarico, a Christian whose Christian beliefs challenge theirs.

If you're a monk planning to go on a peace walk, it's highly recommended you bring along an adorable little peace dog. 🐕

Dear Pam Bondi, (A Letter From A Father) Dear Ms Bondi,

I wonder how a human being finds themselves in that chair in front of the watching world in a moment of such gravity, so completely bereft of empathy, so seemingly unencumbered by other people’s suffering, and so strident in the face of accountability...
