Cognition has been redefined already: not just slime mold that use bacterial signalling methods, but also plants: There are youtube videos of plant leaves getting munched by insects, the munched part emits these polypeptides/neurotransmitters, which diffuse to other parts of the leaf in about 5-10 minutes, causing the entire leaf to emit bug repellant. It's sped up 100x so you can see it happening, and the chemical reaction is tagged with phosphorescent tags, to make it visible. There are also results on the computational abilities and problem solving by tree roots -- these also communicate, often using mycelial matts from mold to do so -- so, like nerves, in a way. Biologists are all over this kind of stuff. Here's one: search for TED talk "quorum sensing" -- I get Bonnie Bassler -- I think that's the right talk. Go for the full-length talk. An a related note, check out "Algorithmic botany" -- http://algorithmicbotany.org/papers/ -- it spells out in detail exactly how Turing machines, algorithms, grammars, syntax, Lindenmeyer systems, bacterial quorum sensing and plant development work -- complete with math. Prusinkiewicz has been working on this since the 1980's. You might learn the most, by reading the oldest papers first, and only then moving to the newer stuff. --linas On Sun, May 22, 2022 at 1:10 PM Mark Wigzell <[email protected]> wrote: > https://groups.google.com/g/opencog/c/Bfjvh_WFVq0 > > I understand that from a formal ai perspective its not a challenge maybe, > I was enamoured with the basic sentience following along causal chains. > --Mark > > On Sun, May 22, 2022 at 10:41 AM Linas Vepstas <[email protected]> > wrote: > >> Hi Mark, My email inbox is slammed, I missed it. -- resend? -- linas >> >> On Sat, May 21, 2022 at 11:07 PM Mark Wigzell <[email protected]> >> wrote: >> >>> Hey Linas, I wrote you a while back about slime molds, did you see that? >>> I was hoping to hear your opinion on the subject. >>> Cheers, >>> Mark >>> >> >> >> -- >> Patrick: Are they laughing at us? >> Sponge Bob: No, Patrick, they are laughing next to us. >> >> >> -- Patrick: Are they laughing at us?
