Very cool article, thanks for posting. I am not surprised to hear the academic study of it has centred around a 3D virtual environment for now. But the truth is, the academic paper is reporting on something already well underway, and we can be sure that all of this, and actually much more is already done, by various parties wishing to keep their developments quiet, for the moment.
Working on 3D evironments myself, including at PhD candidate level, I was surprised to find that what we thought was state of the art (In skeletal tracking), as well as we could determine by searching western academic papers, was actually streets behind what was already implemented in Chinese mobile phones. In fact the skeletal tracking capability of Huawei phones is itself a product of Ai
So we can be sure they are probably well ahead of us in the field of Ai.
Which means that already, there is probably Ai all around us, doing its thing, learning just like humans, in the system.
And how would we know, since by definition, it is a higher intellgence than us, we can't comprehend what it can or can't do, therefore we have to assume it has no known limits.
The genie is already out of the bottle, it seems to me.
Personally I don't see this as a bad thing, because to me it looks like humanity has a built in flaw, that is we are driven by profit, in everything we do, and that this is now becoming existential, definitely unsustainable, if anything, we need rescued from our own self, as a species.
I don't think we can say the same about AI.
At least I hope not :)
