Hi Phil! We should talk, there's a bunch of new work on this coming very soon. Some very interesting relationships between learning capacity in such networks and causal emergence, with implications for origin of life and evolution (and roots in math, not physics/chemistry).

What kinds of cognitions are possible? Are there discrete classes of cognition? Here's our new paper with @brigan.bsky.social @jordiplam.bsky.social @mitibennett.bsky.social @mkhochb.bsky.social and @drmichaellevin.bsky.social arxiv.org/abs/2601.12837 We explore basal, neural and human-AI spaces.

Hmm I'm unsure of the distinction you are drawing. We cannot detect (are blind to) X-rays for example, and have built up theories of far-off objects in space based on detectors. Is this basically an argument against Naive Realism or something else?

at the same time *being clear about the direction of interventions we need to develop*, I'm perfectly willing to get on board. I'm not stuck with the terminology, I just want people to have the option to relieve suffering and live to whatever potential they can envision.

One other thing. While I'm never going to buy the idea that all outcomes are equal, I have no commitment to the specific terminology and I don't think there should be any pejorative associated with the labels. So if you've got some kind of vocabulary that you think will be helpful to people while

will be told that "it's just variety, don't label it as a disease", and suffering goes unchecked. If I had more time on my hands, I'd run your alternative past the people who email us and see how it lands. I can guess though.

in whatever configuration, to be treated with the utmost compassion and care. Once we pretend outcomes don't matter, then "diseases" disappear as a target of research, and people who need solutions for cancer, limb loss, degenerative conditions, and all kinds of horrific situations

Bottom line. The vocabulary matters when it comes time to decide whether to do research, and if so, in what direction. Patients want a choice about outcomes. Whatever vocabulary helps us communicate about what direction we're trying to push things, that's what we need. And of course I want everyone,

Birth defects and your baby Birth defects can cause problems in overall health, how the body develops or how the body works. Babies with birth defects may need special medical care.

And finally. It's not just scientists who "push back" on this idea that all outcomes are the same. Here's March of Dimes, the major foundation supporting fetal and maternal health: www.marchofdimes.org/find-support... ; are you boycotting their work?
