feels like there is a group of smart and well-intentioned people who long ago made up their minds that AI Is Bad, swore off using it, and now get all their info about AI from each other. not saying they're wrong that ai is bad! but i think they're gradually losing touch with what it is and does

Education research is broken. AI can help us fix it.
Mistakes and overreach are common in published research, weakening the field’s role as a purveyor of evidence.

New @nytimes.com piece ranks 30 education interventions on both effectiveness & costs. For me, the key takeaway is NOT about what academics (including myself) rated as most effective or least costly. It is about the decision making process districts use. 🧵 www.nytimes.com/2026/09/28/u...

It's time to move on from this outdated understanding of what AI models do. Agentic AI is not just fancy autocomplete. The models can pull data, write code to analyze it, verify claims, create audit trails, etc. It's not error-proof and vigilance is essential, but it's not the ChatGPT of 2024-2025.

AI models are very different. We don’t actually know how they work. Despite more capital investment than for any technological endeavor in history (roughly 50 Manhattan Projects after adjusting for inflation), we are, in some sense, flying blind. open.substack.com/pub/brendanb...

LLMs will usher in a democratization of intellect. Now you too can have a junior (AI) scholar that you can blame for errors and fraud. Previously, only the top scholars had access to that kind of power.

Assuming you're using agentic AI tools, my default work mode is now: every single task is an opportunity to figure out how to get Claude to make that task easier/better for me. Anytime it works well, save it to claude.md so that it just does it automatically next time.

Fascinating study and a demonstration of one of the deep challenges with LLM-based AI models: because they are trained on human-generated text, they can exhibit patterns resembling human cognitive biases (e.g., anchoring) even in clinical contexts where the stakes are high.

What many don't yet grasp is just how quickly all of these things—the good, the bad, and the ugly—are coming down the line. AI models have reached capability that allows for basically anyone with an internet connection to spin up functioning apps using just ideas expressed in natural language.
