Another thing that I think people have overlooked is that Airiam got infected by a Control that was from 500 years in the future. But how much of sentient control could have made the journey from the future into equipment that's half a millenium less advanced. I see it as Its kind of like trying to fit Windows 10 into a 8086. Its clearly got some protocols running, such as 'get the sphere data' and 'remove Burnham from the equation' but like Nomad, is it really capable of effectively distinguishing Michael from her mom? Does the merging of 23rd and 28th century Control really work the way 28th century Control wanted, just like Nomad didn't end up working properly when it was merged with the alien probe it connected with and mistook Kirk for Roykirk?
