I Think Venti Is Immune To Erosion And Might Be An Agent Of Erosion
I think with the recent updates, it's pretty safe to say that Venti is immune to Erosion, unlike other beings in Teyat.
The NPC in Dorman Port heavily implies this to be true, as well as Nicole's statement about Venti's memories being reliable, which affirms that he isn't affected by Erosion. He's also never shown to worry about being affected by erosion, unlike Zhongli.
Coincidentally, I was playing through the Aranara Quest right before 6.5 dropped, and boy, there are so many interesting details there about memory and corruption. As well as references to wind and time.
The first quote definitely asserts that the winds are unchanging and constant, and that they are everywhere. The second quote is what makes me believe that the wind could be an agent of erosion. This shows that the wind is carrying these memories away fyi leads to them being forgotten. But this quest is about the withering, so I decided to go check out Zhongli's story quest once more to see if I missed anything.
Kun Jun is Azdhaha, btw, that's him in that human. This was at the very end of the quest, where he and Zhongli were talking. Time is what causes erosion. We know that the wind carries the memories and presence of all creatures to Time. And at the end of the quest, the wind is present when erosion was taking its effects on Azdaha.
I think that might be a consequence of bringing memories to Time. The wind is the agent of Time's Erosion. Another thing that could support this is that in real life, erosion is caused by the wind and water.
Anyways, what do you think? Do you agree?
