I, for one, welcome our long duration, unmanned orbital overlords.

No PU-238 means no more missions like Cassini-Huygens and pretty much anywhere that the sun doesn't shine enough to power the satellite via solar cells.
The article notes that the only other source of PU-238 is Russia — either through the government or through trolling through Siberia and the Russian coastline looking for old Soviet Era lighthouses and power stations.
