It’s basically impossible to create conciousness when we don’t even fully understand what conciousness is or how it works.
I disagree here. Things can happen by accident. Doubtful but possible. Nothing I have seen has been conscious to me certainly.

… and this wasn’t made by accident, it was deliberately engineered to develop emergent behavior. Quite a lot of money has been spent hiring a variety of experts to make it do this thing.

Hasn’t worked. Almost certainly will never work, with this particular kind of network. But we would not have known that, just by looking at diagrams and going ‘naaahhh.’
