Solutions to the decline of Magecraft/Mysteries?

[Ideofago]

Then I believe you've got your answer.

There is no solution.
No solution needed.
Humans very good.
Humanity awesome.
Celebrate Human History.
Cherish it.

Agreed. Mystery was always nothing more than a crutch for when humanity still needed a helping hand. Losing all the magic powers is a small price to pay for being able to choose our own destiny without being bound to capricious gods or mysterious otherworldly forces who cannot be trusted to understand or empathize with humankind.

I thought it was the overconsumption of natural resources and destruction of the biosphere from gluttonous corporate entities that was damning Extraverse. The decline in Mana was why the world powers were trying to fix things with a lunar based alien supercomputer rather an semi-omnipotent wish granting device.

No, it was apparently an attempt to summon the Dark Six ahead of schedule which went wrong in some undefined way. I assume that everything else stemmed from that, somehow- I'm not sure how lack of mana would do that, but I'm not the one who came up with the idea.

No, if anything it's the opposite.

You seem to have misinterpreted what Overcount 1999 is. The "wound on the soul of the planet" caused by Overcount 1999 did lead to the eventual decay of resources on Earth. But the resources themselves is no big matter. That much can be solved by Mooncell. Twice says as much.

However, that problem being fixed won't stop humanity's decline. This is what drove Twice (and Leo as well) to despair. If Leo were to win and his 'preservation paradise' were to become the future of humanity, that would not fundamentally change the inevitable decline of humanity. In Last Encore Your Score, Nasu outright says that the only future possible for humanity is for them to abandon Earth.

Furthermore, Leo's actions informed Twice that even then, Leo having chosen control over progress means that there is no answer forward for humanity.
