Yeah. Cho touches the Engine, says he "sees everything clearly now." Wrathion eats Lei Shen's heart, which had some of Aman'thul's residual power, he says something similar. The Pantheon were trying to possess the Keepers to survive, but weren't able to due to Sargeras' interference, so they just got a touch of emotion and memory. Titan technology, though, seems to want to teach those who operate it, well... how to operate it. Like a car that teaches you how to drive.
