Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.

The length of ads on stuff like YouTube and Amazon Prime is ridiculous. They’re just reinventing cable.

What's the polite and effective way to tell analytic philosophers to stop being so modest about what they do and start making bigger claims about the place of philosophy in the university?
If philosophy gets relegated, it's partly because it doesn't attract a lot of majors, but also because...

Our paper on a neuromorphic algorithm for solving finite element models is out, which is exciting for a number of reasons. But really I want to talk a bit about how this relates to understanding the brain and #NeuroAI. 🤖🧪🧠🧵 1/

Reservoir computing is good for #neuroAI because
1. it avoids the biological implausibility of backpropagation
2. it naturally models temporal dynamics
3. Random recurrent reservoirs naturally sit near the edge of chaos (complexity is good)
I can continue...

About AI in education.
AI has probably only highlighted the limits of the current scholar system, based on tests, grades, and knowledge.
If we think that teaching and studying are aimed at passing a test or getting a high grade, then AI has probably already won.

This is a great input I received. To respond that:
1/ Social influence doesn’t stop at politics or media—it’s present in science too.
Scientists are not immune to bandwagon effects—repeated claims in literature can start to feel more “true” (illusory truth effect), even when replication is weak.

Silence, please
In 1994, Mr. Rodgers made a prescient point: our information-overloaded world leaves too little time for quiet reflection.
