apparently it was prospective and randomized. I’m a little shocked by the effect size.

And "LLM's just make plausible looking but incorrect text" is silly when that text is more correct than the average adult a large percentage of the time.

I have no idea about AGI but honestly how can you use claude or chatgpt and come away unimpressed? It's like looking at spaceX and saying golly the space winter is going to be harsh because they haven't gotten to Mars yet.

A somewhat sophisticated person says something like the above.

People who change the world will wonder there’s something there. especially given the sober and candid examination of possible confounding factors and mechanisms of action.

This is fantastic. What a sentence to get to write.

This is one of the more insightful comments in this thread. The risk is not merely that Sam’s investments are not diversified, it’s that Sam has competition from more sophisticated capital. Truly passive investments often scale (and get more passive with scale). That scale attracts a lot of capital that can afford lower revenue, higher risk, and better expert knowledge.

Professors will rail against imprecision to undergrads and young graduate students but they use it all the time in real life.

I can already hear my professors saying "stop commenting on style, what do you have to say about substance?"

Your criticism reads like someone accusing economists of being outrageously misleading when they don't sample individual households but measure macro indicators. It's like saying Ramon y cajal was ridiculous because he couldn't image the neuropil effectively. Or like saying early optogenetics experiments were ridiculous because who knows if you're stimulating a neuron in a realistic manner?

And in any case, it's true that synapses are comically small relative to voxel size, but we also have some reasonable information about projection patterns and synapse number from various tracer or rabies studies with which you are no doubt familiar.

I haven't read the nature paper the press release is about and I'm not a huge fan of many d/fMRI practices or derived claims. And I've worked with enough mammalian dwi data to be skeptical of specific connection claims. But this strikes me as a rather interesting result even if you can't measure all the synapses at the right resolution: either the tractography method has connectivity conservation artifacts baked in, or there's something interesting going on.
