The Germans have a word for this, “Fachidiot,” and Japanese word for this is “専門バカ”:

One of the biggest puzzles about our current predicament with fake news and the weaponisation of social media is why the folks who built this technology are so taken aback by what has happened. Exhibit A is the founder of Facebook, Mark Zuckerberg, whose political education I recently chronicled. But he’s not alone. In fact I’d say he is quite representative of many of the biggest movers and shakers in the tech world. We have a burgeoning genre of “OMG, what have we done?” angst coming from former Facebook and Google employees who have begun to realise that the cool stuff they worked on might have had, well, antisocial consequences.

Put simply, what Google and Facebook have built is a pair of amazingly sophisticated, computer-driven engines for extracting users’ personal information and data trails, refining them for sale to advertisers in high-speed data-trading auctions that are entirely unregulated and opaque to everyone except the companies themselves.

The purpose of this infrastructure was to enable companies to target people with carefully customised commercial messages and, as far as we know, they are pretty good at that. (Though some advertisers are beginning to wonder if these systems are quite as good as Google and Facebook claim.) And in doing this, Zuckerberg, Google co-founders Larry Page and Sergey Brin and co wrote themselves licences to print money and build insanely profitable companies.

It never seems to have occurred to them that their advertising engines could also be used to deliver precisely targeted ideological and political messages to voters. Hence the obvious question: how could such smart people be so stupid? The cynical answer is they knew about the potential dark side all along and didn’t care, because to acknowledge it might have undermined the aforementioned licences to print money. Which is another way of saying that most tech leaders are sociopaths. Personally I think that’s unlikely, although among their number are some very peculiar characters: one thinks, for example, of Paypal co-founder Peter Thiel – Trump’s favourite techie; and Travis Kalanick, the founder of Uber.

I would actually argue that some in the tech field are willfully blind because their paycheck depends on this lack of awareness, while others are blind because they feel that they are somehow above such “mundane” concerns.

In either case, they aren’t people that we can trust with our future.
