English needed spaces because the graphemes are of variable length, so without spacing there is no telling in any quick way where one meaning unit ends and another begins. The idea that Chinese "needs" spacing is a little like a UTF-16 advocate saying "what UTF-32 really needs is surrogate pairs". No, spacing is not some kind of high tech invention by English, it's a necessity that follows from the its special design (also think the use of null characters to terminate strings)
