I'm not sure. If we think about it mechanically, and the output of the a computer system is a function of it's input, then perhaps we are woefully underestimating the role of the body as both a monitor and input system.
Self-driving cars have rudimentary visual input, proximity sensors, location data, and other inputs.
Like we don't even have a full conscious understanding of what we are made from, or what we need to survive.
How do we 'install' those ideas and that imperative in an agent, when we don't fully understand it ourselves?
I'm not entirely supporting one side or another, but I think it's reasonable to bet against the imminent arrival of AGI at this stage, unless some radical discovery comes to light soon.
And if (when?) that discovery eventually comes, I'd suspect it to be a biological one. But then, who knows...
Many who practice meditation and/or experiment with psychedelic drugs will tell you that there's something in there that's not a computer.
We could assume, as many do, they're fooling themselves; since we can't measure it. Or, we could trust our authentic experience of the real world even when it can't (yet) be measured.
