why rat neurons and not people neurons?
It's explained in the video. Rat neurons are more than enough for this application and are much cheaper to come by.

I’m not sure a more fundamental point is explained or addressed: when forming ad hoc networks like this do we expect anything different at all with human neurons ?
One way address that is to grow the as organoids. You can think of organoids like 'cells growing in a non-flat surface'. This mean the cells would have all 3 dimensions to grow and form connections.
The problem with that is that you need a LOT o cells, and they are expensive. The way around it is to create neurons from skin cells. But that has its own set of challenges.

the video is half an hour long. probably the worst way to convey information

I.e. one can also quickly verify if it is for the wrong target.

Well, that's horrifying
At first: how horrifying to subject brain cells to the world of Doom!
After more info: oh, they don’t perceive the horrific setting nor possess the context to know they are in a simulation. They just have inputs and outputs, comfort and discomfort. That’s not so bad.
Upon deep reflection: oh God! We are just a scaled up version of this! Our perception of the world is just a tiny slice of reality filtered through limited senses. For all we know we could be trapped in a simulated hellscape with no chance of ever breaking free!

Opinion that's years out of date:
* The biosafety level is lower (all human tissue is automatically BSL2 or BSL2+ because it might have HIV and stuff)
* The best neural cultures (neurons + supporting cells) come from actual tissue, there aren't good stable immortal cell lines for neural cells. So this generally means fetal cells which for human tissue involves a boatload of process and bureaucracy. Fetal rats, *comparatively* have little bureaucracy.
* iPSC cells (Induced Pluripotent Stem Cells / "stem cells harvested from adults") can generate neural cells but it's several stages removed, and still more process overhead if it's human tissue
* It's better to harvest actual brain tissue than grow them from progenitor lines. You can grab partially or fully differentiated cells by dissecting them out of specific locations (i.e. hippocampal neurons, dopaminergic neurons, ...). Forcing a population of progenitor cells to develop into what you want is a massive pain / still an "unsolved problem" in the sense that you can't buy a grow-a-brain kit. (NOT facetious, most labs that aren't dirt poor use kits as much as possible and it is TOTALLY worth it)Well, that's horrifying
It’s a funny one. At first: how horrifying to subject brain cells to the world of Doom!

Other videos on his channel is also quite interesting
