HI!
I don’t know if anyone will read this as all the comments seem to be at least a decade old. I was linked to this post from another about total user counts on the site. I’m an 18-year-old computer science student from the UK, with a keen interest in self-improvement and rationality.
This site has continually amazed me with post after post of creative, thrilling, eloquent and in many cases practical insights. As much as I recognise my slight perfectionism, I’m waiting until I can really contribute something of value so that I don’t diminish the excellent quality of posts and comments on the site. AI, in particular, is something I’m extremely excited about, and I hope I can contribute to this site and eventually to the field at large :)
This isn’t extremely relevant, but what makes you think superposition/polysemanticity isn’t present in the brain? There’s evidence that L2/3 pyramidal neurons can learn to represent/disambiguate many spatio-temporal patterns: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6354899/.
