This is just confused. He appears, perhaps, to be using "OS" as a metaphor for "basic conceptual approaches" or maybe for "common assumptions and attitudes" --

This is just confused. He appears, perhaps, to be using "OS" as a metaphor for "basic conceptual approaches" or maybe for "common assumptions and attitudes" -- but if that is the case it is just impossible to imagine what kind of "breakthrough" he hopes to get. Or, if it is talking about actual OS's, which one(s)? Does he even realize there are different OS's in phones, in laptops, in embedded systems? What kind of "breakthrough" does he imagine would change all of them?
