... Unless you try to actually model and simulate actual neurons, and everything that plays into those systems, and then try to build a digital brain out of them, and then study how that goes.

'Whole Brain Emulation' is an existing, entirely distinct approach to attempting to create AI... and well, now its gone from little discussed niche to basically 'lost media' status, as these LLMs sure are enthralling for capitalists who like to pump out slop for the masses, aren't they?

I love how we all just decided that LLMs = AI.

Turns out most humans are too stupid to pass a reverse Turing Test.

Which most of us neuroscientists hated because a neural network is a biological network. [...] Conflating the term with research on actual neural networks.

Yeah that's fair, co-opting the term in computing was bound to overtake its original definition, but it doesn't feel fair to blame that on the computer scientists that were trying to strengthen the nodes of the model to mimic how neural connections can be strengthened and weakened. (I'm a software engineer, not a neuroscientist, so I am not trying to explain neuroscience to a neuroscientist.)

mostly because they called it “neural networks” which sounded super cool.

To be fair... it does sound super cool.

It boogled the mind how anyone could believe a prediction model could have consciousness.

I promise you the computer scientists studying it never thought it could have consciousness. Lay-people, and a capitalist society trying to turn every technology into profit thought it could have consciousness. That doesn't take AI, though. See, for example, the Chinese Room. From Wikipedia, emphasis mine, "[...] The machine does this so perfectly that no one can tell that they are communicating with a machine and not a hidden Chinese speaker." Also, though it is from a science fiction author Arthur C. Clarke's third law, "Any sufficiently advanced technology is indistinguishable from magic." applies here as well. Outside of proper science perception is everything.

To a lay-person an AI Chatbot feels as though it has consciousness, the very difficulty with which online forums have in telling AI slop comments from real people is evidence to how well an LLM has modeled language such that it can be so easily mistaken for intelligence.

There is no understanding. No thinking. No ability to understand context.

We start to diverge into the philosophical here, but these can be argued. I won't try to have the argument here, because god knows the Internet has seen enough of that philosophical banter already. I would just like to point out that the problem of context specifically was one that artificial neural networks with convolutional filters sought to address. Image recognition originally lacked the ability to process images in a way that took the whole image into account. Convolutions broke up windows of pixels into discreet parameters, and multiple layers in "deep" (absurdly-numbered layer-count) neural networks could do heuristics on the windows, then repeat the process to get heuristics on larger and larger convolutions until the whole network accurately predicted an image of a particular size. It's not hard to see how this could be called "understanding context" in the case of pixels. If, then, it can be done with pixels why not other concepts?

We use heuristics

Heuristics are about a "close enough" approximation for a solution. Artificial neural networks are exactly this. It is a long-running problem with artificial neural networks that overfitting the model leads to bad predictions because being more loose about training the network results in better heuristics.

Which further feed emotional salience (attention). A cycling. That does not occur in computers.

The loop you're talking about sounds awfully similar to the way artificial neural networks are trained in a loop. Not exactly the same because it is artificial, but I can't in good conscious not draw that parallel.

You use the word "emotion" a lot. I would think that a neuroscientist would be first in line to point out how poorly understood emotions are in the human brain.

A lot of the tail end there is about the complexity of human emotion, but a great deal was about the feedback loop of emotion.

I think something you might be missing about the core difference between artificial and biological neural networks is that one is analogue and the other is digital. Digital systems must by their nature be discreet things. CPUs process instructions one at a time. Modern computers are so fast we of course feel like they multitask but they don't. Not in the way an analogue system does like in biology. You can't both make predictions off of an artificial neural network, and simultaneously calculate the backpropogation of that same network. One of them has to happen first, and the other has to happen second, at the very least. You're right that it'll never be exactly like a biological system because of this. An analogue computer with bi-directional impulses that more closely matched biology might, though. Analogue computers aren't really a thing anymore, they have a whole ecosystem of issues themselves.

The human nervous system is fast. Blindingly fast. However computers are faster. For example videos can be displayed faster than neurons can even process a video frame. We've literally hit the limit of human frames-per-second fidelity.

So if you will, computers don't need to be analogue. They can just be so overwhelmingly fast at their own imitation loop of input and output that biological analogue systems can't notice a difference.

Like I said though the subject in any direction quickly devolves into philosophy, which I'm not going to touch.

I haven't found that even my 8 or 5 year old ask if the robot is sentient. They all get it. You don't have to worry.

Isn't this like saying the dictionary is knowledgeable because it knows more words than you?

it doesn't predict, it follows a weighted graph or the equivalent. it doesn't guess, /dev/urandom input makes the path unpredictable. any case where it looks like it predicts or guesses is purely accidental, and all in the eye of the observer.

further, it only posses knowledge to tthe degree that an encyclopedia does. the prompt is just the equivalent of a hash key pulling a bucket out of a map.

it is literally just a huge database of key-value pairs stored so as to minimize the description length of the values.

Does the "free range" stupidity cost more?

Yes, all the same people who thought smartphones were actually "smart" or that social media was actually "social" are the ones thinking artificial intelligence is actually "intelligent". Just cause a company calls their product "vitamin water" doesn't make it healthy, and the sooner people learn to see through the bs hype machine that major corporations have us all hypnotized by, the better for everyone.

You’re entirely right, it might be harmless. Or it might render the entirety of the planet into mittens because no one decided to set limits on its purpose or means. Even the most seemingly benign mistakes could be world altering
