I’d say the complication of the book “Why? Software and Coding” is kinda frightening.

The side-character (the programmer) lost his progress on a project since his nephew snagged a wire to the power, with his backup also getting lost (again by his nephew), leading for the side-character to redo it for 2 days until he got sick and had to be brought into a hospital.

This is on a kids comic, by the way. (also, no, the accidents are all unintended, it’s not like the nephew is scheming it)
