The paper seems to depend on this claim:

> One of the leading critics was the philosopher Hubert Dreyfus, who argued that computers, who have no body, no childhood and no cultural practice, could not acquire intelligence at all.

So, I don't understand how the argument is at all credible. We have computers that do this. They are called robots. It may be the case that the best route to AGI is to put a robot through childhood. It would need an advanced enough learning framework first. All ML research is currently hashing out what that might be.
