Nahhh that's just a myth XD Only the more modern electronics based versions have that problem but the older types are hardware based so they actually have a cancellation effect on each other whenever they register the presence of another sonic field resonation.
i would have nerd envy... but i'm not sure i want to be that nerdy. i mean, if it's memorizing more decimal places of pi or learning to program various computers, sure. but knowing that much about a fictional technology?..
Well, thing is I made all that up XD The most nerdy I go is making up fictional information about stuff by stringing together tech words. It's called technobabble. Ten was really good at it I think. Just practice your technobabble but stick to Doctor Who if you do. Trekkies will actually expect you to KNOW what your technobabble means D:
Star Wars can suffer the same way. Try talking to a fan about the windows in Palpatine's office in Episode three and see how many people argue that they shouldn't have shattered because they're not glass but transparisteel XD
