> Humans being manipulated is not, in and of itself, a hint that things are going wrong.
Well, if this is meant to counter the abstract's claim that:
> Modern smartphones are designed to manipulate the attention and behaviour of users in ways that further the interests of the corporations that built them. In this they are importantly different from resources typically associated with the extended mind—such as notebooks, Scrabble racks and maps—which are not designed to manipulate or exploit users
I think it falls a little short of refuting a claim that in this particular case things are going somewhat wrong.
