Second it's the blog author the one who fails to acknowledge said military attacks caused by the plane wandering away from its route, which is very much pilot error.
As another commenter noted, the blog author does acknowledge one of the military attacks was caused by the plane wandering away from its route. YOU, however, say "said military attacks", completely missing the author's other point that one of the attacks was when an NK operative planted a bomb on a plan in ABU FUCKING DHABI. Furthermore, he didn't deny that they were pilot error. He denies that it is a KOREAN CULTURE error. Gladwell's thesis about the Korean language was plain wrong. Your "pilot error" is not even wrong.
In fact the write up in that blog is so biased and the overall tone so inflammatory that the original story should be modded -1 Flamebait.
There's nothing wrong with bias. As for inflammatory, maybe, if you have comprehension problems, as you evidently show.
So then why would a civilization capable of advanced space flight go out of their way
Can't they just stumble across us? Do they have to go out of their way?
and through all the trouble of finding a population of quasi-intelligent apes to farm for brain power when they could likely just as easily grow brain matter on a computing/communication substrate that can be controlled, specialized, and reproduced at will with enough resources?
Maybe consciousness is more complicated to develop than advanced space flight?
Human brains, for all their wonderful complexity, are the end result of evolution, a process notorious for using hacked-together "good enough" adaptations. Engineered tissue from the ribosome up could be made much more efficient. Hell, replacing the axon's chemo-electrical method of signal transduction with something more along the lines of metallic or carbon nanotube circuits would improve efficiency many times over; nerve transduction has been clocked at only 170 m/s, peanuts compared to modern silicon processors.
Maybe it's not just a matter of electrical efficiency? Say what you like about human brains, but as far as we know, have only evolved once on Earth in 4 billion years, whereas eyes evolved at least 40 times. There is something to be said about a brain that's hacked together that can potentially understand relativistic equations.
A lot of scifi is bogged down with the concept of aliens needing something from Earth, but this concept is mostly not plausible. Water is everywhere. Minerals are everywhere. No, they don't even need to eat us. If you can cross space by whatever method, you have probably figured out food or evolved or engineered yourselves beyond the need to eat constantly like humans do.
What if the aliens require massive computing power? The large mass of sentient brains of this planet could be a very rare thing in the cosmos. Complex chemistry for life is common all over the universe. Maybe multicellular life is also common in this universe. But a massively parallel simulating biological computer is probably rare enough to encounter that it's easier for them to coopt rather than engineer.
It's not hard to imagine, at least for me, that an alien race may find it easier to build on biological computing technology than it is to keep pushing the boundaries of physics for smaller non-biological computers.
A computer scientist is someone who fixes things that aren't broken.
