OK, but 900 years from now you’re gonna wish you had stayed at the ground floor.

A thousand years. I wonder how they settled on that number. Let me guess, it was a joke that shouldn't be taken too seriously.

Given that the text reads like it was written by someone inhaling a lot of NO2, I wouldn't take it 'seriously,' but I wouldn't take it as a 'joke', either. I would take it as 'sign of insanity.'

I was referring to a well known political party that also had a thousand year plan. I wonder if Eth Org will get cut down to just 12 years.

That's not a very good joke. 'We're comparing ourselves to the Third Reich! Hahahaha!'

It's right there in the word you used: millennium. The referent is truly ancient. Ancient Zoroastrianism held that history is a cycle of periods of 1000 years, each ending in heresy in destruction. Judaism and Christianity inherited this concept, and there have always been strains of Christian millennialism, the most literal of which hold that Christ will rule on Earth for literally 1000 years, until the last judgment. That is why it is resonant.
