Hmmm, not sure how I missed this...
The article linked gives precious little data on the exact way SpiNNaker is going to mimic neurons. That's the first hurdle. They call it a "supercomputer" which to me implies digital logic... if so, it's a lost cause. The brain is analog.
Looking at the photo, it looks like a bunch of racks. If that is SpiNNaker, it's not going to work. The brain is not compartmentalized like that.
The text describes each neural unit as having "moving parts." That is concerning to me as a neural unit need not have any moving parts... indeed, such would only interfere with proper operation. My design calls for solid-state units.
A million 'neural' processors also seems like a small number. If it did work with that many, it might have the intelligence of the amoeba people are arguing about.
Let me see if I can explain this without getting too technical or giving too much improper disclosure. This concept, if it is what it sounds like, is something I started working on many many years ago. As it turns out, according to my calculations, it is indeed possible to create a type of intelligence artificially using the blueprint of the brain. The trick is in getting artificial neurons to react in the same manner as organic neurons.
The neurons themselves are not where memory or thought is stored. The neurons are simple analog processors for data. The storage is the interlinking between the neurons. In an organism, this happens by dendrites moving toward axions and making contact, strengthening or loosening the contact depending on the signals received. While that mechanism appears to be difficult if not impossible to recreate artificially, similar mechanisms may be employed which could perform an equivalent function.
There are two methods to implement this artificial intelligence system: the most accurate would be using discrete neural assemblies, but that would require numbers of them into the billions. My design could hardly have them called 'processors' in the true sense of the word, because they do not process data as we normally think of processing data. At the inputs and outputs, all data is analog, not bits or bytes. Internally, since a storage system is required for analog data, it might be useful to include a digital memory and AD/DA converters, but that would certainly increase an already astronomical cost. That cost is exactly why I have not attempted actual construction.
Now, it might be possible to use a digital computer to simulate the artificial neurons. I have considered that, but the number of threads and memory requirements are both, again, astronomical. The resulting program should react similar to the actual device, allowing for the analog-digital uncertainty that is inherent in such conversions. That may be their goal, but it forgets one important thing: the sensors.
An organic brain is tied inextricably to a massive number of sensors: touch, temperature, taste, audio, vision, pressure, and on and on and on. I saw no sensors in the photo (still assuming the photo was indeed of SpiNNaker). Without the sensors, SpiNNaker is an isolated brain with no way to read or write to/from the world of reality. It will do nothing; it can do nothing, because there is no input to produce an output. Input to a neural computer would not be in the form of a keyboard or mouse... it will need organic-based sensors to support an organic-based brain.
I mentioned the racks above... that will not work if this is a version of my design. All the processors would need to be tied together, not linked through communication networks as a rack arrangement would require, or the communication network would have to be extremely fast and have an unbelievable amount of bandwidth. Again, I am basing this on the photo, which may or may not be the actual machine.
Even with a million neurons and the astronomical number of potential interconnections, that million neurons pales alongside the number which would be required to produce enough intelligence to study. it might... might... have the intelligence of an amoeba.
And finally, I want to address the idea that it will somehow be able to think, imagine, and reason. No, it won't. The artificial intelligence I have been working on only explains the Pavlovian intelligence... as in, the intelligence to learn from one's surroundings and act accordingly based on past experiences. There is another aspect to intelligence: the aspect that allows us to think, imagine, and reason. I have seen no indication in my studies that this form of intelligence is even capable of being housed in an organic brain. My best guess at this point is that it exists outside the brain and somehow communicates with the brain. My work is limited to the Pavlovian intelligence.
This is quite interesting, to be sure... I really want to see what the scientists discover, but to understand their discoveries I would need much more information on how they created it. Perhaps when I get time, I will look up more information on this, but for now I think they have invented a toy that might at best indicate how to build a better unit next time. This is at best just a small step, but it could be a step in the right direction.

That's why proof is so important to have, to see, to show, in every case. It is truth.

Okay, let´s reset the conversation we had.
My whole point was, you can´t be sure what´s happening behind closed doors. As much as I would like to give you anything, you will have to wait for an official report.
I admit that I could have been more friendly to you but you. I understand that you have a problem with hyping things that are not portrait like they really are. I´m with you on that.
But this is exactly the reason why I am so into this and discussing. The terms used, starting from intelligence, over artificial intelligence and all the other things have to be taken into context.
I dislike overhyping AI as much as you do and the thought that feelings, sentinent is an intrinsic feature of an AI (this time, I reference on human intelligence) is just as laughable to me as it is to you, for example.
But you give me the impression that you use those terms too loosely. We ended up arguing about semantics and lost the oversight.

In the 'ant-species' case, there would be no reason for any of them to 'take precautions' against a hazard, since this requires reasoning - an ability to know what to do, in order to avoid harm, for its survival. Machines are not alive, they are incapable of actions for their survival, because they are not alive to begin with.
What I'm trying to get across, in the end, is that this technology is very dangerous to us. I see it being used against us, to allow them to unleash great horrors on the world, with no repercussions, because the world will lie in complete ignorance of the reality. As we've seen before, on 9/11, and other events. All I can hope for, is that people start to wake up, before it's too late.

Adapting to conditions as you describe it is indirect processing, which is not intelligence at all, only the appearance of individual thoughts/responses. I do agree with you on there being no actual thought, or reasoning, or dreaming, though.
Motor response is what you are referring to, as Pavlovian intelligence. Not the same as indirect processing which allows a machine to either go to, or avoid, any pre-selected stimulus -this is not intelligence.
