Even if that was true, do you think it would be hard to hook it up to a Boston Dynamics robot and potentially add a few sensors? I reckon that could be done in an afternoon (by humans), or a few seconds (by the AGI). I feel like I'm missing your point.
Well, we don't know how hard it is. But if it hasn't been done yet, it must be much harder than most people think.
If you do manage to make a thinking, working AGI machine, would you call it "a living being"?
No, the machine still needs to have individuality, a way to experience "oness" that all living humans (and perhaps animals, we don't know) feel. Some call it "a soul", others "consciousness".
The machine would have to live independently from its creators, to be self-aware, to multiply. Otherwise, it is just a shell filled with random data gathered from the Internet and its surroundings.
