There was (and still somewhat is) a big uproar about auto tune usage in music. But guess what? You haven’t heard a song NOT using it since at least 1998. Unless youre friends with every sound engineer out there and can ask them specifically if an artist did or did not use it (unrealistic).
The same will happen with ai. People wont notice, and it will go on to be the norm, with a very small pocket of purists.
Pitch correction totally is a replacement for the specific skill of singing on key, though. While it’s not the only skill that goes into singing, it’s one that society used to admire in a good singer. Pitch correction also removes many small deviations in pitch that may have been appreciated by listeners as part of the artist’s performance. Just because everyone’s doing it now doesn’t mean something subtle and real hasn’t been lost.
