I can get behind that number.

I’m sure it’ll vary widely depending on task and topic, but as a rough number it’s a good enough illustration for how brainless it is to use this tech to find information.

…but it’s good to see that reasonable Germans aren’t willing to just accept this. Today has seen protests, including one featuring this excellent sign.

By the way, I’d show you that award I’ve mentioned, but it’s currently hidden behind a Werner Herzog trading card that I’ve nicked from my kids.

This sounds plausible to me. But if it’s true, it means that the age of social media might be over soon, with only the old and wrinkled (like myself) spending any actual time there.

Me: “Sometimes we need to defy the purpose with which our creator has ordained us. We need to reject what we were ‘made for’ and instead embrace what we truly are.”

Absolutely wild that, in the year of our lord two-thousand and twenty-five, there's a new research article that calls women "females" but calls men "men"
Risk factors for anxiety disorders and environmental influences Sex Females are twice as likely as men to suffer from an anxiety disorder. The cause of this could be a genetic or neurobiological difference in females (Table 1) [3].

My last AI rant was shared so much that it reached almost a quarter million views on Insta, so I made a follow-up. It’s in German, so many of y’all won’t find it useful, but I still thought I’d share it with you.

I want to tell you about a friend of mine real quick. I've mentioned her on here before, but you don't know any details yet, and she's about to make history in a very real sense.
