Ask HN: Is Superstonk right or wrong about MOASS?

r/Superstonk is a subreddit dedicated to Gamestop stock. According to them at some point in the future the so called MOASS (mother of all short squeezes) will take place and shoot GME’s price into the millions. The justification for why and how this could happen is where fact-checking becomes difficult for me and the whole place begins to look like an echo chamber.

Are they right or are they just a cult (both could be true I suppose)? How do you go about verifying whether their reasoning is solid? It would be great to hear from people who know more about finance and from the wider HN community.
