LLMs are an obvious dead end when it comes to actual “intelligence” or understanding how the world works.
But, this sounds like a “draw the rest of the owl” situation.
“JEPA learns abstract representations of how the world works, ignoring unpredictable surface detail.”
Oh, it’s that simple is it? Just have it “learn abstract representations of how the world works”. Amazing how nobody thought to do that before!
I think I understand the distinction they’re trying to draw. Current models are trained on billions of pictures of cats and billions of pictures of dogs. You feed it an image of Fido and it finds a point in 2500 dimensional space and knows whether that point is in the “cat space” or “dog space”. It can be very good, but it doesn’t have any “understanding” of what makes something a cat vs. a dog. Humans, OTOH, aren’t trained on billions of images. But, they learn about things like “teeth” and “whiskers” and “snouts” and “eyes”. Within their knowledge of eyes, they spot that vertical slit pupils are unusual and different, and part of what makes something “catlike”. AFAIK, nobody has ever managed to create a system that learns abstract features without intensive human training.
I like that they’re trying something new. But, are they counting on a massive breakthrough on a problem that has existed since people first started theorizing about AI? Or, is it just a matter of refining a known process?




Really, silver shouldn’t even exist until players are level 5-6 or something.
A copper shouldn’t be thought of as a penny, but I think a lot of people think of it that way. It should be much more like a dollar. A mug of ale is 4 copper pieces. A loaf of bread is 4 copper pieces. A taxi is 1 copper.
Because D&D is a world without cash registers or price stickers, bargaining should be common. And you’re not going to bargain over the last penny, but maybe over the number of dollars (i.e. coppers).
I also think 1 silver should be 100 copper. But, you should only start seeing silver once you’re dealing with people who are used to dealing with things costing hundreds of “dollars”. 100 copper would be a pain to manage, so they use silver. A typical adventurer’s pub might only rarely see silver because all their prices are in copper, and there’s nothing even approaching 100 “dollars” on their menu.
In this system, gold similar to $10,000 per coin. Because of that, the only kinds of stores that might see gold coins are high end magic shops, or shops dealing with upper-level nobles or royalty.
I also think it’s hard for people to put themselves in a mindset of a “medieval” sort of world. We’re used to a hotel room being hundreds of times the cost of a loaf of bread. That’s a modern thing where both farming and baking are automated. In the past things weren’t nearly that efficient. So, if a poor quality stay in an inn (you’re sharing a bed with other random guests, and there’s a thin mattress) is $100, a loaf of plain bread should be $10.
