Unfortunately disk space is still expensive and rather limited, its unfeasible to really preserve YouTube in any meaningful sense. Maybe someday, like Google Video, YouTube videos will disappear forever.
Perhaps we may have a data revolution before the point of having to delete this old content arrives. I remember watching something on the possibility of storing data within DNA ( the long-term storage possibilities looked very promising not that long ago ).
Is there any other exciting tech which may be on the horizon / advancements in this field?
