I suspect the type of person who is even aware of this 4GB blob is the type of person who would research its usage. Pretty high venn diagram crossover.
Yeah. The fictional user doesn’t know anything about AI but knows about this 4gb file…because of news stories about how bad a 4gb file must be. Outside of that, they don’t know or care and wonder if that means that need to add some more “memory” to their computer.
