I personally don't think we're getting anything. I always saw the "it takes time" point as a way to duck the issue until the community would forget about it entirely.
So, all in all, if you really want to get some answers, maybe wait enough time to give LMG more than enough time to investigate; so much so that using the "this wasn't a reasonable amount of time" defence strategy would be impossible, and then try to get the community to care again. And ask for answers. I personally do not see this happening, ever, but I hope I'm wrong.
Yeah, it is one of the least bad uses for it.
But then again, using literal tera-watts-hours of compute power to save on the easiest actually recyclable material known to man (cardboard), maybe that's just me, maybe I'm too jaded, but it sounds like a pretty bad overall outcome.
It isn't a bad deal for Amazon, tho, who is likely to save on costs, that way, since energy is still orders of magnitude cheaper than it should be[^1], and cardboard is getting pricier.
[^1]: if we were to account for the available supply, the demand, and the future (think sooner than later) need for transition towards new energy sources... Some that simply do not have the same potential.
