Taryn Simon collaborated with Russia’s State Atomic Energy Corporation (ROSATOM) to prepare a work of art made from nuclear material. In the year 3015, approximately one thousand years after its creation, a black square made from vitrified nuclear waste will be permanently displayed at Garage in a custom designed void that has been integrated into the new museum building.
Bold and optimistic of the artist to assume humanity would thrive for that long.
Though I imagine that very thought is more likely the purpose of the art.
Like the 1160 year German art project.

The only way this will ever get finished is if they form a religion whose goal is to build and worship the pyramid. Otherwise they forget why they even started putting blocks down and then some developer will eventually buy up the plot to build an Aldi3000 on it
And they even designed a place for it in a museum building. Wildly optimistic.
