"LLMs are simply tools that emulate the communicative function of language, not the separate and distinct cognitive process of thinking and reasoning, no matter how many data centers we build."
Is language the same as intelligence? The AI industry desperately needs it to be

I wish I didn’t have to share this. But the BBC has decided to censor my first Reith Lecture.
They deleted the line in which I describe Donald Trump as “the most openly corrupt president in American history.” /1

Solar’s price drop is astonishing: panels are now 98% cheaper than when I first analyzed them in 2004.
Today, building a fence with solar can be cheaper than using wood.
