I have played around with electronics and radio equipment, which has given me the opportunity to see (and hear) radio frequency interference. I'm not an expert in the field, so I don't know how much it would take to create critical problems. Yet I know enough about electricity and radio to know that these are physical devices that are bound by the laws of physics. Bit's are more than 1's and 0's that flow along copper pipes. They are varying electrical signals that create electromagnetic waves. Radio isn't a perfect sinusoidal wave the go from point A to point B. They are modulated, and often creep beyond the frequencies that they are allowed to use.

The wonderful thing about modern technology is that we rarely need to think about how it works. The dangerous part is that we think that how it works is irrelevant.
