great Next Generation episode with a great ending

I've seen the "Star Trek: The Next Generation" episode Ship in a Bottle more than a few times, and it's definitely one of my favorites. It was just on again tonight, and I never get tired of the ending. It's almost philosophical.

"As far as Moriarty and the Countess know, they're halfway to Meles II by now. This enhancement module contains enough active memory to provide them with experiences for a lifetime."

"They will live their lives and never know any difference."

"In a sense, you did give Moriarty what he wanted."

"In a sense, who knows? Our reality may be very much like theirs. All this might just be an elaborate simulation running inside a little device sitting on someone's table."

(all but Barclay leave)

"Computer, end program."

(nothing happens)
