I am very skeptical of this idea that people will be able to write but unable to produce useful digital computers.

I agree. When I first saw the post and the mention of humans in the reading end of the loop, I though "maybe there is a scifi story here". Hard to imagine a scenario that left humans but not many artifacts except caches of paper (or other "printed" media). Maybe a remote tribe of uncontacted people (or another species altogether) inherit the Earth after a modern world apocalypse kills off everyone in the technologically more advanced world.

A civilization starting from scratch would still need to develop a fair bit of math and tech/science sophistication before understanding and starting to use artifacts left behind. In particular optical/color on paper scanners would have been difficult before the 20th century.
