We have been "making" nuclear waste that will "last" for eons, though.

Hopefully the constructions (both technical and social) where we store it, in the hope of a future generation that can rid of it, will last centuries too.

I'm convinced everything surrounding nuclear waste is where humans are putting the most effort in thinking and planning for ages. Or, I hope it is.

That said, someone once told me that e.g. castles "back then" where built for centuries, not decades. People thought much more in family-lines, generations and long lasting tribes, than individual, or families' lives.

And there too, nuclear waste is where current society had to think of the grandchildren of the grandchildren, rather than 'before I die'.
