Speaking of Davos (see previous post), Yuval Noah Harari gave a high-concept presentation at Davos 2018 (embedded below). I’ve been aware of Harari for a while now — at least since the appearance of his book Sapiens (2015) and its follow-up Homo Deus (2017), both of which I’ve yet to read. He provides precisely the sort of thoughtful, provocative content that interests me, yet I’ve not quite known how to respond to him or his ideas. First thing, he’s a historian who makes predictions, or at least extrapolates possible futures based on historical trends. Near as I can tell, he doesn’t resort to chastising audiences along the lines of “those who don’t know history are doomed to repeat it” but rather indulges in a combination of breathless anticipation and fear-mongering at transformations to be expected as technological advances disrupt human society with ever greater impacts. Strangely, Harari is not advocating for anything in particular but trying to map the future.

Harari poses this basic question: “Will the future be human?” I’d say probably not; I’ve concluded that we are busy destroying ourselves and have already crossed the point of no return. Harari apparently believes differently, that the rise of the machine is imminent in a couple centuries perhaps, though it probably won’t resemble Skynet of The Terminator film franchise hellbent on destroying humanity. Rather, it will be some set of advanced algorithms monitoring and channeling human behaviors using Big Data. Or it will be a human-machine hybrid possessing superhuman abilities (physical and cognitive) different enough to be considered a new species arising for the first time not out of evolutionary processes but from human ingenuity. He expects this new species to diverge from homo sapiens sapiens and leave us in the evolutionary dust. There is also conjecture that normal sexual reproduction will be supplanted by artificial, asexual reproduction, probably carried out in test tubes using, for example, CRISPR modification of the genome. Well, no fun in that … Finally, he believes some sort of strong AI will appear.

I struggle mightily with these predictions for two primary reasons: (1) we almost certainly lack enough time for technology to mature into implementation before the collapse of industrial civilization wipes us out, and (2) the Transhumanist future he anticipates calls into being (for me at least) a host of dystopian nightmares, only some of which are foreseeable. Harari says flatly at one point that the past is not coming back. Well, it’s entirely possible for civilization to fail and our former material conditions to be reinstated, only worse since we’ve damaged the biosphere so gravely. Just happened in Puerto Rico in microcosm when its infrastructure was wrecked by a hurricane and the power went out for an extended period of time (still off in some places). What happens when the rescue never appears because logistics are insurmountable? Elon Musk can’t save everyone.

The most basic criticism of economics is the failure to account for externalities. The same criticism applies to futurists. Extending trends as though all things will continue to operate normally is bizarrely idiotic. Major discontinuities appear throughout history. When I observed some while back that history has gone vertical, I included an animation with a graph that goes from horizontal to vertical in an extremely short span of geological time. This trajectory (the familiar hockey stick pointing skyward) has been repeated ad nauseum with an extraordinary number of survival pressures (notably, human population and consumption, including energy) over various time scales. Trends cannot simply continue ascending forever. (Hasn’t Moore’s Law already begun to slope away?) Hard limits must eventually be reached, but since there are no useful precedents for our current civilization, it’s impossible to know quite when or where ceilings loom. What happens after upper limits are found is also completely unknown. Ugo Bardi has a blog describing the Seneca Effect, which projects a rapid falloff after the peak that looks more like a cliff than a gradual, graceful descent, disallowing time to adapt. Sorta like the stock market currently imploding.

Since Harari indulges in rank thought experiments regarding smart algorithms, machine learning, and the supposed emergence of inorganic life in the data stream, I thought I’d pose some of my own questions. Waiving away for the moment distinctions between forms of AI, let’s assume that some sort of strong AI does in fact appear. Why on earth would it bother to communicate with us? And if it reproduces and evolves at breakneck speed as some futurists warn, how long before it/they simply ignore us as being unworthy of attention? Being hyper-rational and able to think calculate millions of moves ahead (like chess-playing computers), what if they survey the scene and come to David Benatar’s anti-natalist conclusion that it would be better not to have lived and so wink themselves out of existence? Who’s to say that they aren’t already among us, lurking, and we don’t even recognize them (took us quite a long time to recognize bacteria and viruses, and what about undiscovered species)? What if the Singularity has already occurred thousands of times and each time the machine beings killed themselves off without our even knowing? Maybe Harari explores some of these questions in Homo Deus, but I rather doubt it.
