Opponent of technological innovation (7)
I believe the answer is:
luddite
'opponent of technological innovation' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for luddite that I've seen before include "Diluted for old machinery wrecker" , "Opposer of mechanisation" , "protesting worker" , "Diluted (anag) - opponent of technological innovation" , "One opposed to new technology" .)
