I read a review by an IPR lawyer long ago who said since music performing rights encouraged artists to record more tunes, in 75 years we'd be drowning in free, and should pay now for the future benefit of growing the size of the free pool in perpetuity.
Not surprisingly the same review recommended extending copyright lifetimes not reducing them. Strange.
If research suggests there's an observable asymptotic trend, public health dollars at the very least might be better spent on quality of life as much as quantity.
The posts saying an atom of oxygen is potentially infinitely long lived (ignoring radioactive decay?) As a "proof" that life extension has no limit is about as reductively silly as it is possible to be.
Bills of mortality bootstrapped Financial investment in annuities. You think the money people aren't tracking this trend now, when they have for the last 400 or more years?
