Best explanation I've seen so far for Hemi cam/lifter failures

I didn’t watch the video but, asked a service mgr at the dealership today what he thought about it. I was discussing my 2019 Ram with 5.7. He says they see it at 20k or 150k miles or not at all with nothing consistent. He says change your oil regularly. That’s what you can do to minimize the chance. He says it’s bad metal in the pin for the roller. Nothing official though.
