Is autotune use in songs a negative influence?

When Cher came out with Believe in the late 90s/early00s, it heralded a new age in vocal instrumentation. Today, with the prevalence of autotune in many popular artists songs and it becoming a dominant force in chart music, do we think that autotune enhances the vocal experience or detracts from it?
Does the use of digital technology take away some of the emotional authenticity of vocal music? I think its a worthy debate considering the trends in modern popular music, and the changes in the music industry that have taken place since the dawn of the internet.
