He prob missed that the Vulcans are written as badly flawed characters, not ideal ones.
And that people who insist they are hyper-rational and try to reject emotions are usually just not aware of the emotions involved in their decision making.
In Beezlebub's Tales, there's a made-up term 'Hasnamuss'. It refers to someone who is real intellectual, and therefore thinks of themselves as the Homo Superior -- but yet has a diminished sensitivity and capacity to relate to others. They have lots of information, but no understanding, due to a lack of experience managing real life situations involving other people. This makes them some of the most dangerous people on the planet.
There's a parable about how humanity, at one point in prehistory, manages to overcome all these ego-related issues like vanity, territoriality, paranoia, the collective madness that drives us to war, etc... but then it gets destroyed when a hasnamuss invents politics.
I can get where the desire comes from - I too once thought that the world would be better off if we were all just rational computer-people. But emotions are an important component of processing how things really are - by blinding yourself to them, you're operating at diminished capacity.
Like, this vaguely reminds me of one of the Dok's recently bumped threads about epistemology but a different angle.
Theres this thing that is the plague of the XX and XXIst century, its what is called "instrumental rationality"... its what was briefly discussed in a scene of Jurassic Park.
"You guys were too busy asking yourselves HOW to ask yourselves WHY? or should we even at all" When instrumental rationality is set in motion, reason is reduced to a "technos" (or whatever the term is), a mere tool to the hand that guides it... sure we can digitalize and make automated machines to take your fast-food order, and thats very futuristic and cool, nevermind all the employees we fired in the process! PROGRESS!... thus, science is a rational and objective endevour, guided by the drives or emotions of greed and exploitaition.
Besides, science always has this arrogance of being "objective" as if the subject does not exist, allegedly hygienizing subjectivity from the process... but what is deemed worthy of being researched, the objectives of the research, what questions are asked and how the research is conducted, it all can be traced to a subjective will and drive.
The Ego in itself is the psychical entity that embodies rational instrumentality, which is merely a tool of the unconscious Id or the Superego... a rational executioner of irrational drives.
