U238 may have an obscenely long half life, but that also means it has an extremely low level of radioactivity (it'll kill you faster by chemical toxicity!) The actual problem with the Chernobyl reactor are all the stuff in it that has a much shorter half life, and therefore is outputting much more powerful radiation. Think of it like a lightbulb: if you have a set number of kilowatt hours, you can shine a little bit for a long time or a lot for a short time. U238 is a tiny LED, some of the stuff in the Elephant's Foot is a floodlight.

This is rather overstated. The radiation danger mostly resides in the fission bi-products and the danger is because they produce lots of radiation by decaying quickly. That means the danger does not persist for billions of years, but it does persist for hundreds of years.
I find this sort of hyperbole very annoying because it obscures and confuses the substance, and in this case the substance is very, very serious.

Uranium 238's half-life is not a problem. U238 is not highly radioactive and is not difficult to manage. The problems are the plutonium and the fission products. For instance, strontium-89 and strontium-90 are produced in similar quantities in fission, and each nucleus decays by beta emission. But 90Sr has a 30-year half-life, and 89Sr a 50.5-day half-life.

⚠⚠⚠This is a VERY MISLEADING VIDEO. ⚠⚠⚠
It tends to let you think that Chernobyl will be a problem for billions of years. That is not the case! Uranium 238 is not the problem here, just remember it exists in nature and it is weakly radioactive.
The problem of Chernobyl is the highly radioactive material that makes up the corium, not U238. It was extremely radioactive indeed after the explosion but its half life is a lot shorter: decades, maybe centuries, but certainly not billions of years. Chernobyl has already lost a significant part of its radioactivity.
Remember:
If the half life is long, the radioactivity is weak.
If the radioactivity is strong, the half life is short.
It is very misleading to mix both and this video is as close to a lie as it can be without actually being a lie.
