I dunno, they have arc reactors and self-renewing energy streams. I imagine a Farnsworth is old school to them. It's the encryption of the signal that might be too advanced for any of us, god knows I've tried ever since arriving to get it to work. I can hack anything, invent god knows what, and annoy Artie all without blinking, but encrypting a radio-wave is eluding me (before you ask, yes, it works in my universe, and I refuse to believe in a universe with self-renewing energy sources that encrypting a radio-wave is impossible).
ah! found it!. This all makes perfect sense. Explains why we have our memories of ourselves before we came, but nothing of being here.
