Really hoping human brain cells don't necessarily create consciousness, in this case.

> hundreds of thousands of live human brain cells A human brain has like six orders of magnitude more cells than that chip. A single ant has 250,000 neurons. A crow brain has 1,500,000,000. I don't think we have to worry yet.

Imagine that every individual cell is conscious, and that consciousness is a binary quality.

But how would you know? With a patient who has locked-in syndrome they can sense and think but have no ability to move or communicate. How could you tell if your fish brain (or future AI model) has the capacity to think or suffer?

"current systems are too primitive to feel or understand." Is there evidence to suggest that if it can feel or understand, that would actually be an issue? Every day millions of sentient beings are killed for human consumption and millions more wait in torturous conditions. It would be odd if there was outrage over a bio computer, but not over, say, the practice of using cows and pigs for food, which feel pain, have…

It would not be odd. Outrage is emotion, and logic has little impact. Especially dealing with groups rather than individuals. But even individuals will rationalize their boiled-alive lobster dinner, which is normal in their worldview, while decrying something new they impulsively dislike. And then forget the rationalization entirely, because that is how brains work. Getting the untrained to adjust their worldview, the model of the world their minds use to make decisions, is really difficult as the brain actively defends the model that has worked well so far.

Agreed. It unfortunately wouldn't be odd at all.

I was able help with Christpiracy.com which has some wild mental gymnastics on display.

Imagine that it isn't. What use is imagining something without the slightest shred of evidence?

Panpsychism in various forms has historically held sway with many philosophers. It’s really the Occam’s razor for consciousness.

this is very good news. does it change the ethical concerns if we are using them to transport consciousness to other planets instead of just using them in a lab? I think it does. nature is pretty savage. extending consciousness off world as best we can seems like a natural imperative. I have the sense that programs for organic machines may ultimately resemble music as well.
