I think this is to a degree a generational thing. I guess between 15 and 25 we are imprinted with what lo-fi means to us.

My prediction is that after low quality compression we will see good, but noticeable auto-tune as a retro effect. I don't mean the early, late 90s overdone Cher-like auto-tune, but the one that's used seriously for pitch correction but is still noticeable.

After that, I think, bad vocal synths are a good candidate. To my old ears many are right there in uncanny valley - too human for a synth, but not human enough not to be creepy.
