Absolutely this. But the final form of this requires some input from the reader – front camera access and retina scanning presumably. It may evolve, without proper curtailing, (unidentifiable ads aside) to be a pretty powerful tool of motivation / pacification / manipulation.

Don't know about this, I have slightly more faith in people's ability of appreciation. Though I could be embarrassingly wrong.
I feel (a little hyperbolic allowances, if you will) it's in the books for an Infinite Jest type of entertainment to arise, be it in kindle or netflix form. That is, a piece of entertainment so excruciatingly entertaining, that people will literally and completely drop whatever it is they were doing before (or, you know, just miss a week of work for the sake of the most intimate and powerful writing they've ever experienced) and bask in the glories of their own personal god revealing truths of the universe to them.
Not everyone, in fact I dare do say the majority, don't want to read hyper-personalized content to the point that only we can read it, most of us don't even know what we want, and sometimes that doesn't even matter.
Hyper personalization isn't the end game - at least in my opinion. In fact history has shown that we valued precisely the opposite, collective experience with low enough resolution so we have room to fill the gaps ourselves. How can you relate to others what only you understand?
Or we will eventually cease to be humans?
I didn't understand the "optimism is cowardice" part. The true optimism is believing we will survive long enough to reach that point :P
