CS Lewis said that ""All language about things other than physical objects is necessarily metaphorical." I can't find the examples he gave, but from your sentence: we must "discover new means of interaction that take advantage..."

"Discover" is made of "dis-cover", meaning "remove the things covering the other thing." The "inter" in "interaction" implies movement between objects in a physical space. To "take advantage" evokes physically grasping something.

Perhaps this is more philosophical than you wanted, but I doubt we'll be leaving behind physical metaphors anytime soon.
