I've read the abstract and disagreed with it enough that I don't want to read the article proper.
1) The abstract appears to be an opinion piece; I don't know how they do things in philosophical journals but I would hope for a dryer standard.
2) Nature is really messy - it'd make sense if parts of our bodys were actually parasites. The immune system, gut flora, skin mites are all obvious places where foreign hostile bodies might colonise then integrate into humanity over time. If an addition has any benefits evolutionary pressure will eventually cause it to become symbiotic.
3) Humans are by design easy to manipulate. We're social animals built to group up behind leaders and do what they say. There are brutal social hierarchies where low status humans live relatively unpleasant lives because high-status humans think that is reasonable. We're not built to unthinkingly optimise out own personal outcomes of make all the decisions ourselves. Humans being manipulated is not, in and of itself, a hint that things are going wrong.
4) "It is not plausible for a part of the cognitive system to be designed to thwart the goals and desires of the user in the way a smartphone is" - it absolutely is, the #1 enemy of most people is their own mind. It leads them to do wildly stupid things. There are people who spend their entire lives working to overcome their own cognitive systems to achieve peace and happiness.
> 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.
And now, I disagree with you ;)
> Humans being manipulated is not, in and of itself, a hint that things are going wrong. If a car can be stolen, should it be stolen ? If a dog can be beaten, should it be beaten ? I don’t think because something is fragile that it should be broken, on the contrary. We should recognize the delicacy of our species and design around it. That’d be a sign of evolved behaviour , I’d reckon.
> the #1 enemy of most people is their own mind Again, define the « mind ». Is it really the mental space people live in that is the problem or the culture, teachings, bullyings and programmings that have been thrown at them since birth that are maladaptive ? I’d argue that the mind is fine, given what it can do and that it is just a tool. It is what we do with it that matters and since birth, we’ve been hijacked to fit in society.
