For my part, it is not quite that (karmic benefit). Indeed, it is an indirect
form of egoism. Because, if I know of several people who have taxon X
(because I have distributed taxon X to them), I do not need these
several backup clones to be sure not to lose taxon X by an infection
or other incidents. All I need to do is to call one of the people I have
distributed that taxon to, and a few days later I have it, again.
Kind regards
Jan
