I think it's less about an arc of history and more of an extrapolation. We use technology to advance things that benefit us. Getting people addicted to things benefits the people who sell those things. Hence, they will use technology to advance addictiveness.

We are hitting the fat part of the technology curve, so maybe the fat part of the addictiveness curve is right behind it.
