Just take a look at Ted Stevens' "series of tubes" comment to see the ineptitude of congress. Lets say, for the sake of argument that Stevens was "dumbing it down" for his peers in congress and he was well versed in techno-babble. He himself felt that it was necessary because he felt that his peers didn't know wtf he would be talking about by speaking intelligently and, therefore, they were not capable of making informed decisions. Now, if we go to the side of the coin where we assume Stevens had no idea what he was talking about, then the person attempting to make an argument didn't know a damn thing about technology and we're still screwed.
I, for one, believe there should be some sort of test you need to pass to prove you have basic understandings of certain things before you can represent others. Or, better yet, choose people in the field to make policy; go to MIT, Stanford, IBM, Microsoft, Google, etc and make a tech representation senate. We don't NEED everyone in the government making decisions on everything; spread out the responsibility to those who are experts.
