Note my wording - I said sell it not get rid of it. I think Elon ( or Bezos, or a bunch of other people ) could do something useful with it rather than sinking it into the ocean.

I tend to think of the ISS like a PC - it's infinitely upgradeable, and you replace parts as needed to upgrade them, or add on as needed. (ok, so the ISS is much more complicated, but this is HN, not a PhD dissertation).
