I am little pieces, little pieces, little pieces
Pieces that were picked up on the way
Imprinted with a purpose with a purpose with a purpose
A purpose that's become quite clear today

from Nine Inch Nails – Copy of A Lyrics on Rap Genius

Meaning

Despite what Trent as a being wants, his fate is ultimately guided by the “purpose” of the millions of pieces, each with the same fate: exiting. In the end, regardless of what Trent or anyone else is, his atoms and parts that make him will return to chaos, forming something else. Realizing his fate, independent of his actions, Trent breaks down, letting the pieces have their way. He is lost.
