That they do. I think judging from your other posts that we pretty much agree. Copyright needs serious revision to a shorter time (perhaps fifty years). I think patents are pretty much good as they stand.
I'd say even shorter. But unfortunately there are now financial contracts founded on risk assessment incorporating the premise that copyright is 70+ years. It would be a taking to nullify them by law. What a mass of rotting spaghetti this has turned out to be, supposedly founded with the best of intentions. Only a Constitutional amendment can cure this, and it won't go down easy. This is another reason why we need an amendment to assure Absolute Sunset, so if ignored, bad law just goes away over time (and our legislators will quit screwing around because they'll be held responsible if good law goes away).
