As someone who does have a cognitive disability, there is a genuine difference between augmented input/level skip vs. what is effectively an integrated TAS.

Mario Kart 8 is a good example of accessibility that still empowers the player, as the player still needs to hold an input and retains control of the character - it's just that massive errors that would result in loss (IE: falling off the track) are prevented by corrective steering taking control.

An automated TAS gives no empowerment to the player - it's no different that running a lengthy macro script. If I wanted to watch the characters have an adventure without my ability to have influence in the journey, I'd just watch a movie instead.
