They should put it in orbit, with solar cells to power it and send a radio signal.

You mean, like the Pyramids? Chances of survival.......Lol!

There is even a viable movement acknowledging and celebrating the end. I like it. [vhemt.org]

Will what’s next at the top of earth’s food chain have any use for the contents of the box?

Seems pointless. Anything that could get here would have almost necessarily been able to avoid the evolutionary pitfalls we fell victim to, so they likely wouldn't learn anything. And there isn't enough time left on Earth for humans to die out completely and have something else evolve to the point they could learn from it. It's just going to fill up, stop recording, then melt to a gigantic solar flare or massive asteroid. Maybe those scientists should be working on gene therapy to prevent fetuses from turning into dumb, backward-ass, regressive, Republicans?

What could possibly evolve that could decipher the contents? Human life was an accident. What comes next would be a carbon-based life form, but probably much different.
