Nightmare: Google will use Optimization by Vector Space Methods
Suppose this is done without it being a vector for advert targeting. A really good idea? NOT.
It's one of the SF-inspired nightmares that haunts my imagination. A society optimised too close to the edge of chaos. Then some small thing goes wrong, and it crashes via a set of un-anticipated interactions. Crashes hard. Crashes so hard and with so many interlocks and interactions, that it can never get back on its feet before 90% of the population are dead.
Maybe we're there already, with JIT delivery and internet and computers replacing people in finance and sales. World CyberWar One may be worse than a nuclear WW3. But it could get an awful lot more fragile in the future, if the warnings are not heeded.
Fact. Half of the USA's electricity grid was once knocked out by a suicidal squirrel carbonising itself. But at least there was enough resiliece in that system, that they could (manually!) re-boot the electricity grid over the next twelve hours or so, before the rest of society crashed.
