A lot of comments disparaging this, but it is fundamentally correct. If our civilization as it is survives and does not collapse, then this "manual" is unnecessary. It is only useful if our civilization has clearly failed. Maybe sanitation was a huge mistake. Maybe antibiotics were a huge mistake. Maybe the remnants of humanity that survive the apocalypse will look back on a humanity all but wiped out by superbugs of their own making. Maybe agriculture was a huge mistake. Maybe the march towards monocultures is inevitable, and the remnants of humanity that survive the apocalypse will look back on a humanity all but wiped out by blights or the total depletion of fertile topsoil. For anything that we wish to impart to these remnants, there's a scenario where that is why we failed, because we must assume that we did fail to justify the attempt at the manual at all.
