every day we are farther from God's light
Netflix has announced a new reality series titled ‘THE NEW STANFORD PRISON EXPERIMENT’.
The series follows 30 participants who enter a real prison and are randomly assigned as guards or prisoners. They must see if they conform to the roles or if morality wins.

Once you tune out Ted's voice, this is a very enjoyable 3 min
ESPN had Ted Cruz on 'College GameDay' in a conversation with Rece Davis for nearly 10 minutes.
Cruz was heavily booed by the crowd -- and heard "Ted, you suck!" chants -- in Austin.

In the wake of turmoil at OpenAI and Anthropic, it’s become common to describe A.I. as a kind of person, hatching plans and pursuing desires. The truth is a little trickier. www.newyorker.com/culture/open...

It might have taken another year or two, but I'm pretty sure a couple dozen NSF grants devoted to this one problem would have gotten it done?
