One main issue with language change that prescriptive views have is that if language is the same as it has been for an extended period of time then it is 'normal' however when language changes which is all the time to keep up with current technology, popular uses etc. then it no longer becomes 'normal'
A huge number of words from Dr Johnsons dictionary in 1755 have changed meanings, broadened to gains more and narrowed to loose unnecessary meanings no longer popularly used.
