The problem with awarding only complete works is: bad people exist. Laws need to have enough flexibility so that truly devious people are covered by the law as well. Example: I copy 99% of a popular song, but the first 3 seconds of my song = me playing a trumpet at full blast. Technically it's not a copy of the complete works, so I can argue in court that it's a sub-section of the original song. No judge/jury would agree with me, but my point is shown in this example. Even if you specify your definition sub-section to be < 50%, you would still be unhappy, because I copied half your song. What sub-section is OK? The YouTube/AI issue is that loose/vague laws assume a certain degree of "common sense" among the population. When you try to give a loose task to a computer, it must make assumptions (either with AI, or pattern matching) and will invariably screw up. Computers are not human brains so they don't have "common sense"... yet.
