Well, you're right, that guy is an asshole. But he also makes a point, namely that there is no person in the world with a reason to purchase a Cybertruck other than just to jerk off Elongated Muskrat a bit more. It doesn't do anything practical. Even someone with an F150 or a Ram 2500, while yes they do generally own a parking lot princess, it can do truck stuff in a pinch. It has a bed and a tailgate and it can haul a trailer. Cybertruck can maybe haul a trailer but it isn't going to do anything else practical that a Ford won't. You'll never catch a contractor driving a Cybertruck. You will find them driving an F150.
Point is, he's not saying you aren't real, he's saying the hypothetical person that has a valid use case for a Cybertruck isn't real. If someone is going out to buy a truck to perform work they aren't looking at Tesla.
