Obligatory mention of T-Pain's Tiny Desk Concert, in which he demonstrates, without autotune, that he's a talented musician and vocalist who's using it stylistically.

They really don't, but you've made up your mind so you'll only ever really hear it when it sounds like T-Pain, then go "you see! all sounds like T-pain!"
Since the T-Pain era (known as the ringtone rap era) we've had everything from To Pimp a Butterfly to Flower Boy to Kids See Ghosts to LP!
It's been a decade+ of innovation on a level that makes the old days look mundane.
I have to say that I'm really not a fan of what seems to be "topping the charts" in hip-hop today, but even so, there's undeniably people doing new and interesting things in the genre.
A few releases since the heyday of T-Pain that I did enjoy:
* To Pimp a Butterfly
* DAMN
* Coloring Book
* Kids See Ghosts
* We Got It From Here ... Thank You For Your Service
I've also really enjoyed some of the hip-hop adjacent stuff that Thundercat has put out, especially Drunk. (Thundercat is amazingly talented, and was a big part of the production on TPAB).
