With the rising sea levels due to glacial melt the saltiness of the water is going down, so really this is just doing the fish a solid! /s

Yup, that’s terrible. PSC’s still have a long way to go and we need to find encapsulation technologies to extend their life more, but where they shine is that they should be dirt cheap. If they cost 1/4 of silicon based cells, but only last 1/2 as long, that’s still a massive improvement.
