whenever copyright comes up a bunch of engineers come up with suggestions for fixing copyright that seem to be based on the idea that every country has the same theory of copyright as the U.S. Well I would suggest that the best fix for copyright would be to bring international Non-US standards in line with U.S or some sort of compromise between the two. The main problem I find with copyright is seeing something is in the public domain but later on realizing no, it's in the public domain in the U.S because it was made in 1926 but since the creator died in 1970 it won't really be truly public domain (excusing some potential weird little countries with unlimited copyright) until 2040.
