I did not say it was safe, I said after a few decades is far easier to process. It does not remain "crazy" high radioactive for thousands of years - that is pure hyperbole. The chart attached illustrates radiotoxicity if ingested - and no one advises anyone to eat nuclear waste.
Radioactive material radiates, because it decays. The more it radiates, the faster it decays. The highest level radioactive material from nuclear fission reactors has half-life measured in decades (30 years), that is, half of it will decay in that time. It does NOT take thousands of years. Conversely, the long-lived isotopes radiate much less, thus are easier to store and process.
Hilarious that a #HackerNews top voted comment on a post wrt #Reddit censoring mentions of #Lemmy effectively argues that the latter is "too geeky and hard to use" and that the former two won't be displaced because they're well known and easy to approach.
These people have ZERO self awareness. Never mind understanding about the legacy of their forums.
