Computer-building has turned into this, at least if r/pcmasterrace is any indication. It's positively infuriating -- 99% of people's posts are bragging/validation, there are cliques/cargo cults around 144hz, LinusTechTips, RGB, and watercooling, and I cannot remember the last time I saw an in-depth technical discussion about anything there.
I personally think humans' need to form cliques and ingroups is its worse trait; it has transformed a deeply technical hobby that I love into yet another bragging and dick-waving contest :(
