> On top of the sheer audacious difficulty of creating whole brain emulations, there's the problem of competing with boring old "narrow" AI. Surely an economist of all people should recognize the feedback loop that makes narrow AI profitable first, which attracts more investment, which unlocks more capabilities without biological emulation... how many of today's jobs are going to be left un-done by narrow AI a century from now, even if whole brain emulations are finally practical then?

This is a curious blind spot. With deep learning algorithms making easy work of master Go players, there has to be enormous untapped potential in GPGPU silicon for AI.
