I do believe, very very mildly, that there's a strain of thinking among the tech crowd that glorifies this Spock-like emotional detachment and I'm-so-rational mindset. Two issues, actually:

First, such a mindset is neither possible nor would do much good. There are stroke victims that survive with full mental capabilities with regards to logical reasoning but entirely devoid of emotions. These patients can still ace the SAT, but they fail spectacularly at daily life. As it turns out, you just cannot decide on a doctor's appointment without emotions. They'll spent hours vacillating between two good choices. Emotions are incredibly well-tuned heuristics that cut down your mental load to manageable levels. As any part of being human, they are sometimes ill-fitting for modern times: there's absolutely no reason to make me flinch when I spill hot coffee over my hand. But mostly they just work.

Second, it's slightly annoying when people deny that they are subject to emotions, and it gets up to Ryanair-levels of discomfort when they announce that it makes them superior to all those emotional social science majors, illogical politicians, women "throwing a fit", superficial designers etc. If I got a KDE theme every time someone accused Apple users of being blinded by eye candy, I'd still be left with only half of what Kubuntu ships.

But Rust is cool.

I disagree that this is related to the original posted article about a company that has chosen as their first language Haskell. I do wonder how your responses would differ if they had chosen Elm originally and perhaps it is both you and I that should evaluate our emotions are why we even commented...

I've long-admitted that my heuristics for choosing a tech stack are very similar to what you describe. I analyze the requirements and give each technology a pass/fail grade. Then, amongst those that pass, I simply choose the one that I find the coolest.

Something needs to be a driver for action, and emotions fit the bill nicely.
