It's sort of a weird definition for HLMI since it involves cost. I.e., if you can replace an engineer but leasing the hardware, power etc. costs more than the engineer's salary it doesn't count? This is an important point, because ignoring that it could be the case that the first HLMI requires significant computational power to run - definitely to train, I'd expect, at least. So you can have a 5x human agent on some super computer but you have to build 1000 of those before you start talking about significant impact.
