Cyberstuck

It seems to be some kind of instinct, wanting to be edgelord-y while growing up (asia knows that as chuunybyou). And while some never grow up mentally, some others never overcome the edgelord-y.

I subscribe to the theory that tech bros are deeply insecure about their masculinity because they have basically no genuine manliness in their lives, and the Cybertruck is something they're familiar with (gimmicky tech bullshit) that tricks them into thinking they are doing manly things (hauling building supplies in a pickup truck).

More likely that one of his kids drew it and told him it was a Tesla and so he made it real to support the idea that with money you can do anything.

Teaching them young.
