I always buy my nails from Home Depot. I’m not addicted to nails. Home Depot does not reasonably think they can get me addicted to nails.
It's probably not the nails, but there's a reason people always stick with a particular hardware store.
(Also, I know that's a flip example, but there are absolutely brands of nails and screws I always get).
Addiction is a real thing with a real definition and real consequences and it’s not the same as love or admiration or even fanaticism.
You can say something is "addictive" without implying it's a substance abuse disorder.
When people at Microsoft say the goal of AI is to be addictive, they're clearly implying that they want their product to be habit forming in the same way that video games or food delivery is. And it's silly to imply Microsoft is trying to create physiological dependence.
I really truly, madly, deeply, in the big picture of this, think that you’re wrong. They could choose a different word and they don’t. We could debate the nuances and their are multitudes, but I think the actions of the industry align themselves much more with the accurate definition of addiction then something else.
This would then mean that "our expert witness has strong evidence that my client's product area is not 'addictive', so my client could not ever be said to be engineering addiction" would not be a defense any more than "the plan my client came up with to kill their alleged victim could not possibly have worked, so my client can not be charged with attempted murder" is (at least generally, afaik) not a defense.
Does writing a book aims to make people read addictive? Try to design a gym class that makes you feel good about yourself so you will come again?
You still need to define what is addictive
I don't believe devices are addictive, but that's irrelevant to Satya Nadella believing it and trying to exploit it and thus being a scammer.
It's going to get fuzzy around whether entertaining somebody counts as exploiting their psychology. Obviously it doesn't, but that would rest on reasonably assumed consent.
※ People do get sentenced for attempted fraud, but that's for more blatant things like trying to extract money from an unwitting victim's bank account, rather than just saying "we must figure out how to commit some fraud".
We thereby do not necessarily need a way to know whether reading--either your book or any book--is addictive or not, but only the extent to which you were going out of your way to make it addictive, for which I think it might then be OK to have some specific-yet-contrived definition that is difficult to apply to any specific product but feels like a wrong thing to do (maybe my "exploit human psychology or physiology")?
