I disagree. If humanity collapses, and a new fledgling civilisation grows out of the ashes, then maybe we should let them follow their own path, and make their own discoveries and mistakes.
It's massive hubris to assume that future generations can only survive if they have access to our knowledge.
Many civilisations have fallen only to be replaced by newer betters ones, even when they've had no previous records to refer to.
We're just a stepping stone along the path of human evolution, we are no greater or lesser than the stones before us, or the stones that come after us.
A collapse would be the perfect and likely sole opportunity to ditch the mistakes of the past and forge something completely new with the benefit of a "foresight" forged from hindsight.
