For those interested beyond the new age marketing speak that shouldn&#x27;t exist on any real research company:<p>These are the guys behind Dishbrain, which is not really a brain but a patch of human induced pluripotent stem cells grown on the Maxone silicon chip [2] which allows recording from the entire ~5x5mm chip with high resolution.<p>[1] <a href="https:&#x2F;&#x2F;newatlas.com&#x2F;computers&#x2F;human-brain-chip-ai&#x2F;" rel="nofollow noreferrer">https:&#x2F;&#x2F;newatlas.com&#x2F;computers&#x2F;human-brain-chip-ai&#x2F;</a><p>[2] <a href="https:&#x2F;&#x2F;www.mxwbio.com&#x2F;products&#x2F;maxone-mea-system-microelectrode-array&#x2F;" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.mxwbio.com&#x2F;products&#x2F;maxone-mea-system-microelect...</a>

Ah, sweet. Man-made horrors beyond my comprehension.<p>Hopefully this will lead to brain implants that can help with solving a bunch of brain issues, and not to what we&#x27;re all thinking of.

Never thought the day that brain in a vat is no longer a philosophical question but a practical one would come so soon.

This gives me nightmares tbh. Love that they say that they’re happy and healthy, lol.

So head cheese. Or Bio-Neural Gel Packs.<p>Depending on your sci-fi of choice.

This does not appear to be new or novel technology, aside from the fact that the neurons-on-chip are housed in a portable incubator.<p>Example:<p><a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=1w41gH6x_30">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=1w41gH6x_30</a>

&gt;What happens if we grow a mind native to the infinite possibility space of digital computing?<p>Nothing we need to care about, as there is no such a thing. Mankind has put a significant portion of its limited attentional power on building interconnected silicon computers, that in a space whose scale is so small compared to human bodies that illusion of infinity is easy to fall into. In the same time, mankind went with global policy of massively draw on non-renewable energy stock, destroying vast sustainable life supporting environment in the process. There is nothing like unlimited resources and infinite space.<p>Now, obviously, this page is marketing idle talk, with a weak connection to the actual work in their labs.<p>From a purely scientific point of view, I wonder if that kind of device is just as vulnerable to magnetic storms as a pure silicon based device.<p>From a human perspective, without much more context, this seems just horrific and I wish them much ethical and legal barriers to stop them already.

If the goal is to mimic the human brain, how is this different than just...starting with a human brain? Either way, you will be subjugating a possibly conscious mind into servitude. I am sure they are &quot;happy&quot; (however you want to measure it) about it either way lol

The actual paper: <a href="https:&#x2F;&#x2F;www.cell.com&#x2F;neuron&#x2F;fulltext&#x2F;S0896-6273(22)00806-6" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.cell.com&#x2F;neuron&#x2F;fulltext&#x2F;S0896-6273(22)00806-6</a><p>Of note: This is an active test of the &quot;Free Energy Principle&quot; [1] with seemingly supportive results.<p>Their definition, in the paper, of sentience is as follows:<p>&gt; It is proposed that these neural cultures would meet the formal definition of sentience as being “responsive to sensory impressions” through adaptive internal processes.<p>[1] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Free_energy_principle" rel="nofollow noreferrer">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Free_energy_principle</a>

In the Rifters trilogy by Peter Watts this technology is referred to as “head cheese”. It’s used as a form of AI as it turns out silicon can never beat biology at analog reasoning. It ends up playing a role in the plot.<p>IRL If the masses of neurons start getting large this starts to be ethically questionable… in direct proportion to how large.

It&#x27;s clear that you can get some actual neurons in a dish to behave as an artifical neuron network. It is a fascinating concept as a research question. What&#x27;s not clear is what is the business value here - do they expect these natural networks to outperform ANNs for any foreseeable application?

Surely you&#x27;d just want to copy how the neurons work enough to run them on normal silicon rather than dealing with wetware? Or has that hit a wall?<p>Amazing, scary, and perhaps absurd, all at the same time!

Beautiful website. They massively over-claim on their science though. Their &#x27;tech&#x27; is nothing special, people have been culturing and recording from neurons for years. And their claims of &#x27;sentient&#x27; neurons in a dish should be taken as being somewhat flexible with the meaning of the word.

Just finished watching the Pantheon (2022) series about “uploaded intelligence” last week. Pretty ironic timing!

No ethical considerations to be found anywhere. Typical.

<i>Our biOS composes their reality, sending information about it via electrical signals. It then converts the neuron&#x27;s activity into actions inside that reality. Their world is mediated through our biOS.</i><p>The simulation argument asserts that &quot;at least one of the following propositions is true: (1) the human species is very likely to go extinct before reaching a “posthuman” stage; (2) any posthuman civilization is extremely unlikely to run a significant number of simulations of their evolutionary history (or variations thereof); (3) we are almost certainly living in a computer simulation.&quot;<p>(1) is still possible - humankind is armed to the teeth, this tech could be a bunch of hot air, the breakthrough is still N years away, etc.<p>(2) becomes less likely with every headline. If we had the ability today to simulate a consciousness-filled universe thousands of instances would be spun up overnight.<p>(3) is looking more plausible than ever...<p><a href="https:&#x2F;&#x2F;simulation-argument.com&#x2F;" rel="nofollow noreferrer">https:&#x2F;&#x2F;simulation-argument.com&#x2F;</a>
