In today’s age I don’t think it’s a mistake and also if we do have a future similar to this they not going to stop cursing.One thing that I feel is a mistake is the incredibly forced F bombs.
Star Trek has inspired so many people to become engineers, doctors, military officers, etc. And saying "fuck" gratuitously may cause some parents to not let their children watch the show.
I'm hoping they explain why there have now been Romulans in the show that look like Romulans from classic Star Trek as well as Romulans that look like humans with pointed ears and "angry" eyebrows.
