I kind of want to see someone use fancy AI voice banks that are trendy and hard-autotune them to make them sound more like older vocaloid versions, just to mess with people.
I definitely do like some things about AI voice banks, but let's not lose sight of the fact that pretty much any vocal synth is a rounding error compared to Miku's popularity, which means the concatenative synthesis sound really isn't going out of style. The majority of listeners aren't huge synth nerds who know how the software works; they're just there for singing robots. There's definitely room for both in the foreseeable future.

You're not alone, I'm still using the old voice banks and kind of self conious about using stuff people may consider outdated nowadays. I kind of want to make good on the software I have though and not chase after the new shiny fad.
