When the feels train hits you the first time, you really don't feel any urge to fap. You just... breathe, and walk around a little, wondering what the heck just happened.
Now that it's more than a day since KS got released on these platforms to a wider audience, some of new weebs would have been hit by the feels train and can vibe with this meme.
KS was also the first time the original "I know that feel bro" wojak exploded in popularity (to my knowledge), and that wojak has outlived rageface comics to form a core foundations of memes even a decade later (doomer wojak, depressed wojak, and so on). The impact which KS has had on Internet culture is probably vast and unknown, yet the positive impact it has had on the lives of those that played it is, as shown by the survey, no less vast, and certainly no less real.
KS had some impact on me learning Braille. Okay, perhaps not as much as Aldous Huxley saying that it's comfy to read with your head under blankets, but still.
