Eh, I could see elves being like Dax from DS9. When they get bored with their old lives, they simply reinvent themselves and start anew. In that way they could easily keep up with the times.Oh, I don't mean that conservative = out of touch. Only that old elves should probably be out of touch with the youth. With the faster paced aspects of society and fads and the like. The "Grandpa asking about the Youtubes" angle, specifically.
Needless to say, I don’t agree with your premise. Run elves how you want, not how someone else perceives them. They’re fantasy things anyways.
<Edit> I really feel like @Steampunkette is leaning into Agism. “You are old, therefore you MUST be stuck in your ways”
