Based on my experiences meeting other Trekkies at Phoenix Fan Fusion and Tuscon Comic Con.
Like, once you get past this part, most of the original Trekkies are fun to talk to, but combined with that subset of gen X TNG guys who talk about their college years and give you unsolicited life advice while probably a bit inebriated, you probably lose an hour at whatever convention to hearing this same flex over and over again. 
Also, yes, at Fan Fusion I found out Gen Alpha Trekkies do exist; saw one wearing a DS9 uniform commenting at a panel.
You have no idea how much time people spend trying to get that aesthetic experience these days.
EDIT : "No way dude, it has the 2am infomercials instead of just cutting to black for 2 seconds ! excellent! so retro!" , "yeah, AND it has the noise patterns, so authentic"
