I am in my mid thirties, and a lot of these things are generational..my dad built an enterprise in the late sixties, early seventies, then he built me a few in the eighties, last year I started building the Voyager for my little boy. The demographic in general moves down...hence the eighties (aka when I was little) now being the big thing. But the only way you keep your demographic is if you get younger viewers...otherwise, sooner or later, everyone who grokked Spock, is gonna be dead. Twenty, thirty years tops, original TOS fans from the sixties will sadly no longer be with us. And young kids and young adults spend a whole lot more on geek toys.
They do t like admitting their fan base is getting old and creaky (and varieties thereof if you are talking Who, we have factions in our factions.) BUT they can’t afford to alienate them. Trek has always been good at this precisely because it was generational. It doesn’t need to chase the Game Of Thrones hipster cash, or even the Twin Peaks born again cash, it just needs to keep up with the Joneses and make sure those generations get ‘their’ Trek, which leads them to the others, which make makes it part of a cultural tapestry rather than just an event.
