These guys are about to be super wrong when a couple decades from now governments realize there's a ton of extremely valuable unburned nuclear fuel, ready to be reprocessed, conveniently located in a storage facility.
Most likely in the next few decades they'll figure out how to make it useful or at least not be a problem anymore.
Designing something to last 100, 200 years, alright... but 100,000? We probably won't even be here, on Earth. Waste of time.
> If you work in tech you know that 99% of the stuff you build wouldn't (or shouldn't) last another 5 years.
We have technologies that have survived for thousands of years (agriculture, writing, etc.) This statement is completely myopic and absurd.
If "we" are here, or "something else" arrives at that time they are likely so advanced that the topic of communicating nuclear risks to them is rather pointless.

I can think of at least two scenarios where that's not true: (1) human civilization collapses between now and then, and (2) humans go extinct and intelligence evolves in some other species. I'm sure there are other possibilities as well.
