DX1's story predates Giths.
Err, not exactly. Original manga,
Gost in the shell, was published through 1989–1997.
GitS animated movie by Mamoru Oshii hit the screens in 1995.
Deus ex was released in 2000, so it only predates TV series aka
GitS: Stand alone complex, which is a more detailed manga adaptation.
As a matter of fact, Ghost in the Shell is a Japanese "Lol I can't sp3ak English" mispronunciation of "Ghost in the Machine" a term derived from 19th century writings on Automata, and a term used by British philosopher Gilbert Ryle to talk about mankinds foolish march towards their own untimely destruction by the hands of nuclear weapons.
Again, not exactly so. The phrase itself is surely formed so that it would make an allusion to that Gilbert Ryle's phrase, but it has it's own meaning in the context of GitS. Unfortunately, to fully understand that you need to read the manga itself or, at least, watch some of the TV series. Movies just don't put enough attention to the details.
Also as a matter of fact, Japan hasn't produced an original story in over 2000 years, and even then, it's based on chinese lit (90% of all Anime= Journey to the West). This has to do with the philosophical lock of being based on the 4 books. That's not to say that Ghost in The Shell was not an effing amazing film, nor do I deny it's beautiful imagery, mind bending OMGWTFBBQ type of chaos, or is simply awesome, it's just not quite fair to say they ripped it off. It's the other way around.
To be absolutely exact here, GitS is a japanese adaptation of
W. Gibson's novels, to whom we all owe cyberpunk as a genre. And, frankly, no on in the world hasn't produced an original story in over 5000 years. Everything original was already written by ancient greeks. We now just retell the old stories with new and flashy setting.

P.S.: Sorry for being an otaku here, I just couldn't help myself.
