10 Dumbest Things in Star Trek The Original Series
6. Swiss Army Spock
I wrote a piece on this back in the day (9 Times Spock Got a Power-Up), but Spock's numerous upgrades rendered him increasingly superhuman. Their multiplying abilities were akin to the opening of The Six Million Dollar Man, making Spock “better, stronger, faster…” to the point of absurdity.
He was three times as strong as a human when the script called for it, or when the writers remembered it. He had better hearing. He could knock people out with a pinch. He had an eyesight-saving inner eyelid. His mental discipline allowed him to ignore pain that drove humans to insanity and death. He was less affected by aging than his colleagues. He could handle higher heat and lower oxygen content than a human, but, conversely, was more capable than McCoy of surviving a blizzard in ice age conditions. He could mind meld or mind touch or whatever they called it in a given episode with just about any life form (I'll get to that). It got to the point where he’d pull information out of thin air without even consulting any instruments, and pedantically reported time increments so small that it would be incorrect by the time the sound waves from his mouth reached anyone’s ear.
In short, he became boringly superhuman, with his only Achilles heel his refusal to accept that human emotions had value. In short, the writers made him a Swiss Army Knife capable of whatever a given story required, no matter how dumb.
