It's because a lot of the source material is disappearing Enrique. As long as IT requires to find money to pay electricity bills, it has to be paid to provide hosting services, so if an author or company dies or goes bankrupt, they or it they cannot continue to pay the revenue for the hosting service, therefore the information will be deleted sooner or later to free up the resource for a new party to rent. Then all links to it lead nowhere, because the information is gone, deleted forever.
As said, over and over, it's all part of the destructive system of profit, those deletions go straight to temperature rise because it's increase of entropy to delete information, remember?
There is probably a function that ChatGPT 3.5 (The positive powered version) could produce, which would plot rate of information learning vs information being destroyed, which would reflect exactly the same curve that rate of increase of temperature is following, and it would track more or less exactly, with just a constant multiplier scaling it, and the value of the constant would be the materials destruction including oil and nuclear etc, which are also thrown to heat, adding to temperature increase.
If you doubt what I am saying, try feeding it to ChatGPT, I am sure it will confirm it.
I would do it myself but frankly, I can't be bothered any longer. Everybody is too busy lost in the illusion of a world that isn't really about to self destruct, to see the solution as having any value, and of course nobody thinks they would have had any part to play in ending it, when it dies, in flames, everyone will be pointing at someone else screaming it's their fault, when actually we all played a part in it, except the youngsters, who are innocent, but the system doesn't spare them either, as we can see.
