It seems to me that both this person's own predictions and the predictions of past futurists that he criticises fundamentally fail in the same way: they assume that the faddish ambitions of the day will play out on exactly the timeline that the marketeers tasked with procuring funding for them claim, and largely ignore advances in all other fields. For a century up until the turn of the millennium, the faddish ambition in pursuit of funding was generally spaceflight or AGI, and so authors followed the herd with overly optimistic predictions about that; in 2012, instead, it was everyday convenience tech (as pushed by myriads of startups) and the renaissance of a certain high modernism in the US regarding transit and urban planning.
