Earlier quoted context omitted.

I don't think qualia are real in the general objective case, only in the subjective case. So nobody but 'you', whoever you are, can actually have them.

Ok let's rephrase then: can those mini-brains be a "you"?

I guess if the stem-cells are taken from you as a donor then they would be genetically identical to you as much as twins are genetically identical individuals?

This sounds like an episode of black mirror and seems immoral. If this actually does work and scale the results would be horrific. I don't really want brains with no rights to exist like this.

1/3 of the human brains in the world already exist with no rights. If we can enslave rats instead it will be a big step up.

I think that is a very valid concern, but how could this ever be assessed

If something cannot be assessed, then are we still accountable for the result? Or, do we simply discard the assessment?

Human neural networks definitely are capable of suffering. These researchers might be re-inventing slavery.

> Nagel famously asserts that “an organism has conscious mental states if and only if there is something that it is like to be that organism—something it is like for the organism."

>programmers usually have to engage in a laborious process of manually adjusting the initial coefficients, or weights, that will be applied to each type of data point the network processes. Another challenge is to get the software to balance how much it should be trying to explore new solutions to a problem versus relying on solutions the network has already discovered that work well. “All these problems are complete…

I suppose neurons are already turned for the task at hand. Although I suppose you can change their environment with different chemicals and that would be very close to hyper parameter tuning, after all happy neurons think better.

Or discard the project, since the key variable will remain forever unknowable.

Meaning what? That doesn't bring any light to the question of whether these things are capable of suffering. As someone else said, this is a hard problem to reason about.

This is the point where you end up in the realm of philosophy and phenomenology.

Pretty weird not to comment that they're replicating published work that trained mouse neurons on an electrode array to fly a plane in a flight simulator. https://www.sciencedaily.com/releases/2004/10/041022104658.h... It's about at the level where you could make a good attempt to replicate it as a hobby in your (albeit well stocked) garage.

Very cool, I added this to my 'biohacker' list of links.

And lol @ your Egg Benedict Donburi from Food Wars. I still haven't started season 2... check out Dotchi No Ryouri, it used to run on PBS but can be found on youtube.
