The opposition notified between the world of art objects, connected by Lev Manovich to a romantic idea, and the world of new media art could be understood following a different term of critic.
"As it's impossible that there is a art work whitout being made so [...], as for bill, it can not exists whitout those who safeguards. The fact that a work can not find who safeguards it, or they are not immediately conform to the truth happening in the work, not mean that the work remains active even whitout those safeguardings, even when, and precisely when, it's simply waiting for their input in it's truth. The same forgetfulness in which a work can fall is not a nothing, it's still a safeguard. It lives of the work. Safeguardings of means: staing inside the open-level of being happening in the art-work. But the staing inside of this kind of art-work preservation is a knowledge. But knowledge is not simply in knowledge and representation of a thing. Who really knows what he being is knows what he wants inside it."*
And if here Heidegger is so cryptic, it's only because he's speaking about too far things from us, who usually think about romantic idea of art for first. Seen by his point of view the oppositions of the first quoting are more differences than opposites and due to the social and historical contest.
In next post you will find arguments about technologies used to create art-work by Aristoteles and Lev Manovich.
