There are a few dozen neurons in the bellies of crabs. They control the grinding motions of the stomach.

I would like to see a machine replacement for these neurons that functions just as well as the natural ones before anyone hooks anyone else up to an uploading anything.

Just ... someone please show we can understand how neurons even do things.

It's like building an autonomous drone before you know how to make a paper airplane. (in fact it's much worse than that)

@futurebird I have more or less the same feelings about the “colonize mars” crowd. Build a closed self-sustaining colony in like, Alberta first. Then we can talk.
@steve @futurebird To be fair, Mars doesn’t have Danielle Smith so it might be easier there than in Alberta. Or at least, less stupid.
