Looking for a problem to solve...
"For us, Kinetic storage still has elements of clever engineering technology looking for an end-user problem to solve."
That's what I was thinking immediately / wanted to comment until it turned out to be the last paragraph of the article. Seems more like a toy for proof of concepts, the management issues you'd get at scales with that would be terrible, and you'd need so much effort to manually handle redundant storage in case of failures, and so on.
Maybe as a cheap, proof of concept object storage system for dev work...
I mean, it seems clever, but it also seems to have no real large scale practical application.
