I did read the AEON article and I found it's quite sober really nice.
Thank you, comrade, for the reading material. I do believe that's really the best way to tackle this subject.
I looked a little bit around and the only place I see the following information is on the "I put a fruit fly in Minecraft" video. But, apparently, one of the author's of the Nature paper about the full conectome of the fruitflies did consult the video's author and, when asked about the project, he said "yeah, it's a quite accurate model" when asked about the model neurons they are using for the project.
And, from a bioinformatics standpoint, it's that, a model. It can mimic very well the behaviour of fruitflies, but we don't super duper know why or how. Specially when we just have the conectome (the wiring), not the "software" or chemical state of things at capture, and that's assuming one single individual fly, not all the possible states individual flies could have.
So, yeah, it's a great model, but it's not real.
I'm all in for finding more about the brain, so we can dispell the idea that LLMs are so human like and get on with our lives.
