Let's compare our world models. I find that different people seem to have rather distinct internal world models. E.g. I personally have neither visual imagination nor an inner voice, found it weird others do. Here is a quick google forms to check idea:

World-models in your head
Talking with a lot of people, they have rather shocking different kinds of world-models. I believe that people have somewhat specialized simulators. Let me list some and then give you the chance to ad...

Interesting mystery. It is known that animals can learn to control neurons pretty much anywhere in the brain. But they can not learn to ignore hunger which probably means they can't turn of hunger sensing neurons. How is that avoided in the brain? They even have DA inputs.

VTA DA neurons. I read they have heterogenous projections to cortex. And they have different tuning curves in terms of Reward, punishment, hunger, etc. Computationally it would make a lot of sense that the relevant reward signals make it to the right cortical areas. Known? Computationally important.

Professors: Running a class with research projects? You and your TAs will never have enough time to carefully guide every student through gap, hypotheses, experiment, data analysis, etc. I think every larger course running research projects should use this.
I think almost all scientific projects should be planned carefully. And I think an app can dramatically improve that. So I wrote an app for that (free for now, if you can fund this let me know). I tested it quite a bit (>8000 users in beta so far). try it: planyourscience.com

As we are having a discussion on neural codes: @earlkmiller.bsky.social is entirely right that the "only spike rates matter" idea that is so prominent in neuroscience has no credible evidence. We simply do not currently know how neurons code relevant information. Oscillations are likely part of it.

Put your belief about how ai and bi, capital and labor interact and simulate the economy using our intelligencesaturation.org simulator. Depending parameters you obtain runaway success with wages going to infinity, the evisceration of wages, or everything in between.

AI is growing exponentially at a timescale of months while the economy is growing at a timescale of decades. How should we model the economy with rapidly increasing intelligence tech and slowly increasing physical tech? New AI+econ paper.
