I suspect a human life isn't long enough to place that many blocks.

"(1020 * 260 * 1656) seconds in years" [1] comes out to 14 years. Solid, of course, no breaks or sleep, no time for training or planning or debugging. And one block per second is a pretty good clip for a technical build. It doesn't take many multiplicative factors before it's more than one lifetime.

You would probably also need another lifetime just to fix all the errors once you are finished with laying out all the pieces...
