For (iii) you're probably thinking of Rodney Brooks (aka the co-founder of iRobot).
Since the 80s, he's generally been a proponent of the idea that you can't have human-like intelligence without placing that nascent intelligence in a human-like world, with human-like sensory perception.
Which more or less bears out our experience with deep learning. If you place intelligent algorithms in a world where their sole sensory inputs are matrices then what you get out doesn't look anything like human intelligence.
