(BTW Botvinnik, the first Soviet chess champion, was trying to push his (weaker than competition) chess-playing program as a basis for running the entire Soviet economy (he explained the weakness of his program for chess by it being more general than the competition; it apparently did not occur to him however that the fact that it lost to other machines and of course to people - this was 1990 - could perhaps mean it might run the economy somewhat worse than say a person. He was an engineer.))
As to electing engineers - let's put it this way: all else being equal, I'd rather be ruled by an EXPERIENCED ex-engineer (not just a guy with a degree) with a track record of achieving something, for which people who worked with them can vouch, than an ex-lawyer or an ex-journalist. But "engineer" by itself is not even a certificate of basic sanity, let alone the ability to lead someone somewhere other than the abyss, and for this HN's comment section provides ample evidence on a daily basis.
