The danger is not in letting students use tools like ChatGPT. It is in letting them learn that they don’t have to think, or believing that the tools are smarter than they are.

Now tools that create plausible yet dubious content are ubiquitous, good judgement and critical thinking are more important than ever. I’d like to see teachers help students critique AI-written essays. Find errors, describe what is incorrect or what you would write differently.

I remember Yahoo Answers. While I agree one has limited life experience at 9 years old, it’s entirely possible you still had the best answers on the site.

If I were to give advice to a friend on depression, based on my own experience and that of others I've been close to, it would be this. (I tried to be brief but it's 3 pages.)

The area of emerging research around sunlight/infrared on COVID outcomes seems so significant, widely applicable, and low risk that far more people should know about it. I don't post about COVID much, but since I've seen little on Twitter about this, a 🧵 may be helpful. 1/13

Getting what you want may be a test of intelligence. But realizing you didn’t in fact want what you thought you wanted is a test of wisdom.

I spent 2+ years during the pandemic learning and experimenting with lots of bodyweight/calisthenics fitness programs. Many are great but few give a full picture. So I summarized it all in one chart. It's big. Still a draft. But it's the reference I wish I'd had starting out.

My new theory is that contrarian almost-crazy-but-could-be-true theory building has always been a strength of startup founders. But that same characteristic makes you highly susceptible to LLM-induced delusions. In fact, it’s like some models hunt them out for you.

Depending on who I talk to, I feel either early or late to the party. But if you build with Python and haven't switched already, @astral_sh uv is awesome. Go for it. A quick 🧵 with a few notes and my own project template, in case others getting on the uv train find it helpful.

This is very cool but I have to ask. If it's so new and different, couldn't @AnthropicAI come up with a better name than "the new Claude 3.5 Sonnet"? Like (just spitballing here) maybe "Claude 3.6"?

GPT-4 passing the LSAT or GRE is incredibly impressive. At the same time I think we need a reminder of a logical fallacy we’ll see a lot of this week: That software can pass a test designed for humans does not imply it has the same abilities as humans who pass the same test.

I don't give a damn about what is or isn't AGI. It doesn't matter. Below is GPT-4's performance on many standardized exams: BAR, LSAT, GRE, AP, etc. The truth is, GPT-4 can apply to Stanford as a student now. AI's reasoning ability is OFF THE CHARTS. Exponential growth is the

It is a beautiful font. But in a terminal, my heart still belongs to B612 Mono (with a few modifications to fix its legacy issues).

While packing books today, found one bit of tech history I’m proud to have inherited: The Internet, circa 1982. With the name and phone number of every... single... person.

It’s worth remembering it’s not websites that killed most local newspapers. It was killing revenue models, including bundled classifieds. And it wasn’t feed algorithms that caused Facebook to spread misinformation and divisiveness. It was their incentives to drive ad growth.

Salvational ideology is a hell of a drug. It would be fascinating to travel back in time a century or more to chat with idealistic political radicals (like Marxists during their early years) and compare it to today.
