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 I have a similar opinion, but I'll make an exception to all billionaires who want to move to Mars right now.
@grumble209 @steve @futurebird they are the world's most brilliant minds so it makes sense sending them first. If they can't make it how could we expect some random middle-class person to make it?
