You're welcome! And for sure, about the knowledgeability and eloquence (not to say volubility) of the people encountered by this sort of traveller! :D What a great story it'd make, as a send-up, of an earnest time-traveller encountering good-hearted but unlearned citizens of the future world! (Which reminds me - Jerome K. Jerome did a send-up of exactly this sort of story - the socialist-inspired what-the-world-could-be-like story. JKJ was pretty staunchly Conservative, I guess. Anyway, I'll look for it.)
