If this is the case, then all white collar jobs go away extremely quickly and.... economic collapse happens?

And/Or, if/when they do replace cognition, there's essentially a "laserbeam of genius" and they'll point it directly at muscles and hands again, to replace physical labor.

Of course, nobody knows where this goes, but as a software developer I have never been more busy. I am still worried, but if software developers go down I imagine much of the white collar world will follow, no?
