Will there come a time, in 100 or 1000 years, when the computer will find a 99% match for any creativity from 100 years ago?Every day someone accuses someone of plagiarism or accordion playing, and sometimes it looks very stupid from the outside. For example, one comedian joked about one thing, and now any mention of it is already accordion or theft. Yes, and there is, so to speak, subconscious, unconscious copying, and the probability of coming up with the same thing in a huge period of time is quite large. There are, of course, examples of comedians who steal left and right, but it infuriates when people are accused of plagiarism who have 1-2 examples that barely match.
