Hm, do you have a source for that? It's possible that you're mixing it up with his decision to shelf "micro-voxels" in favor of the traditional, chunkier voxel art style.

Thank you, I think you are right.

Huh, interesting. Even today when there's a voxel discussion on graphics programming communities - john lin comes but all the time

From what I've read (the pinned comment in the aforementioned video), he just decided to ditch high resolution voxels for lower resolution ones, as the feedbacks said they preferred a more pixelated art style. But still voxels. But looking at his latest blog post, it seems that he's not focused on voxels at the moment yet. Or maybe got hired and can't talk about it, who knows ¯\_(ツ)_/¯
