Yes, Ricardo originally introduced the idea of comparative advantage in the context of international trade, in a model in which different countries had different endowments of resources. Nothing that imtringued wrote above suggests he under

Essentially all of economic theory is aimed at explaining, not predicting. The distinction between the two goals [0] is sometimes under-appreciated within the profession, and almost always under-appreciated outside of it. Most predictive to

I think the joke is that Air Marshal Kenneth Porter was chief of the RAF’s maintenance command, and also not a pilot. [0] Edit: fergal_reid’s reply below is correct. Porter did serve several years at the start of his career as a pilot, in t

Right, that’s why I wrote, “I don’t mean that most neural networks are invertible functions.” For a neural network that is not bijective, you can obtain an input that maps to a desired output by the following algorithm. 1. Start with a trai

The obvious solution is to run things in reverse, inputting the AI-generated output to recover the prompt that generated it. Most generative models can be run in reverse by algorithms that already exist [0], but you have to have the model w

The inflection point was 2012, when AlexNet [0], a deep convolutional neural net, achieved a step-change improvement in the ImageNet classification competition. After seeing AlexNet’s results, all of the major ML imaging labs switched to de

Sandvault [0] (whose author is around here somewhere), is another approach that combines sandbox-exe with the grand daddy of system sandboxes, the Unix user system. Basically, give an agent its own unprivileged user account (interacting wit

OK, let’s survey how everybody is sandboxing their AI coding agents in early 2026. What I’ve seen suggests the most common answers are (a) “containers” and (b) “YOLO!” (maybe adding, “Please play nice, agent.”). One approach that I’m about

From what I understand, which is very incomplete, the leading hypothesis at the moment is that ingested prions are a bit hard to digest (because they’re malformed proteins), so they end up making it out of the gastrointestinal tract somehow

I’m not qualified to comment intelligently on what might be going on here, but I’d like to add some background color that the article lacks. Creutzfeldt–Jakob Disease is a prion disease [0] for which there is no definitive diagnosis in vivo
