Everyone (well except for .Dad apparently) knows that. The "I just like the stock" meme is a just that, no one really thinks for a second GME is worth $1000 today, or anytime in the near to mid term. This is a short squeeze, it's not about the company's performance or outlook, not one involved in that move gives a fuck about GME's new CEO or digital shift really.
That being said, I agree that .Dad's argument is nonsense and could have applied to Blockbuster just the same: "this industry isn't going anywhere", "people have disc drives", etc. it was the exact same scenario, big old brick and mortar business not seeing that while people will keep consuming the products of their industry forever, it doesn't mean they'll keep doing it the same way, and therefore do it with them.
Now it doesn't mean they're doomed, but they have to successfully pivot, and who knows how successfully they'll do it and more importantly how big they will be once they're done. Sure, GameStop might not close doors, but they might go from "largest whatever" to just another medium size company in a crowded video game industry, and if you're just looking at the value of the stock as an investor, that's a big fucking risk.
