Yes, I agree.
But I think you need to see it in the larger context. Episode 1, and much of season 1 (series 1 as we would call it here in the UK), is about moving into their world so we get to known them and appreciate them. Jen is the viewers’ guide into this world and her journey towards becoming one of them is the viewer’s journey. So what starts as a laugh at geeks ends up sympathising with the geeks (“but we did all the work!!”) and becoming the geeks (observe how Jen’s office starts as a managers office but slowly ends up with Manga artwork).
So her laughing at the geeks, and her inability to understand them (white noise), is crucial because it takes the viewer’s hand and leads them into the basement.
The most powerful example of this journey is when Jen becomes entertainment manager (“It’s not for you!”) and we have one of the show’s genuinely touching moments , whwn Roy grapples with his breakup and finds release in a session of tabletop RPG. This moment works so well because of the strength of the actors, the script and the fact that it has brought the viewer into the circle; the normies are now loud, obnoxious “business men” who are set free by adopting geekiness.
