I have a collapse-pilled book combo to suggest: The World Without Us by Alan Weisman and The Knowledge by Lewis Dartnell (@lewis_dartnell).

Weisman's book helps you understand just how much maintenance goes into keeping streets, buildings, subways, bridges, petro-infrastructure, and nuclear power plants functional. The depth and breath of effort that it takes to keep the human built-environment together was surprising to me.

If everything collapsed and human technology was lost, Dartnell's The Knowledge would help to bring human infrastructure back on a path without dependence on dirty-power.

After reading both, the absolutely miniscule breadth of your own knowledge will be obvious, which is undoubtedly good.
