Entering PD at death+70y usually means a 100+-20y duration. Does anyone respect this silly timescale? Does any fine been imposed for a forgotten old work?

Compare that with a drug's IP: total of 20 years after the molecule patent, of which 8-10y in clinical trials and only 10-12y in profitable life. But everyone respects that until the last day and it brings billions back.

A short IP time would favor the small/poor creators that could earn something during their lifetime when the work is fresh, while a long one favors companies like Disney which can protect the copyright with their group of lawyers.
