After the fifth tomato, I had to know how my knife did. Without judgment, Heimendinger announced that it placed "second to last in the cohort."

futurism.com Unknown 2025-09-30 08:27:14

Like many conservatives, evangelicals have broadly begun to embrace artificial intelligence — but at the same time, a growing subset of the Christian world is claiming that the technology is quite literally demonic. In a recent Medium blog post — yes, people still post on that site — self-proclaimed "biblical Christian author" and regular AI user Zack Duncan suggested that an image generator's cartoonish outputs regarding Satan may be the result of some demonic influence.

One of the big draws of next week’s Fantastic Four: First Steps is seeing Marvel’s First Family in the retrofuturist Earth-828.

The Switch 2 is in many ways a more premium and powerful version of the original Switch, but its sleek design seems to have come at a cost. Not only is the console itself difficult to repair, but a new iFixit teardown video shows that the Switch 2 Pro Controller isn't any easier.
