I think the author does a rather mediocre job on explaining a point that's IMHO critically important.

Here's Yuval Noah Harari explaining it much better: https://youtu.be/Bw9P_ZXWDJU?t=269

His basic argument is that: 1) free will has always been an illusion, 2) it was an acceptable one because generally no one knew you better than you know yourself, 3) with the advent of mass data processing (call it AI if you want) the premise 2 breaks down, and we should be skeptical of trusting people's judgement. For example, the fundamental ideas underpinning liberal democracies and capitalism ("the customer is always right", "this is what voters want", ...) become unreliable.
