I don’t see why it would ever disappear. It’s essentially a device that transforms your vocal chord into an instrument. So you can sing roughly the tone you have in mind. That’s huge. I often think of melodies that I have no ability to reproduce on any instrument — but I can roughly hit the notes with my voice.

Maybe auto-tune is like guitar distortion and we never get over it.

Auto-tune is like special effects in movies, virtually every movie has special effects but they're only noticed when it's badly done.

I like to remind people the brilliant CGI work in Jurassic Park and Toy Story was contemporary to the cheeseball CGI in made for TV movies. People can guess what's made on a computer in Toy Story, but they never knew the well-done stuff trying to be realistic was done in part or in whole on computers.

The late '90s were especially big here because computers and tools were getting so cheap. The same tech that let big space battles happen in Deep Space 9 and Babylon 5 also made stuff that...did not age so well.

Some people are using autotune as a stylistic choice (for instance Travis Scott and T-pain way before that) which I think is kinda cool.
