100000 years is a very long time. And in that time, you have good chances of reeboting civilization and reconstructing our current industrial world.

Easier said than done, and why would you need to do it, if libraries already solve the problem?

BTW I think we're considering two different scenarios. Libraries are excellent at solving the scenario given here, i.e. the internet collapses tomorrow.
