What makes you say we "probably" won't be here on Earth in 100,000 years? We were here for the past 2,000,000 years. This also ignores the possibility that someone other than "us" will discover what we leave behind.

We have technologies that have survived for thousands of years (agriculture, writing, etc.) This statement is completely myopic and absurd.
It took less than one human lifespan to go from the first powered flight to a man landing on the moon. I see no reason for humans to be stuck on Earth for 100,000 years at our current rate of invention and growth.
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.
Well, the closest potentially habitable planets outside the solar system are lightyears away. Even if we master space travel, I don't see a reason why at least some humans wouldn't stay on Earth, unless it becomes truly uninhabitable. Of course this is speculation about the far future and technologies that don't yet exist, so it's hard to predict what would be likely in that scenario.

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.
