ALL people forget that different people have different priorities and as such will “slack” where others are “diligent”. Our lives have gotten so complex that you would have a hard time finding a single person that does not slack in some areas, deemed important by some subset of society. Sport, nutrition, financial security, education, minimal tech secop, political action (atleast voting), a clean living space, clothing thats considered acceptable, an active social live and the list goes on.

So to summarize, of course “techies” forget that backups are not important to most people. Thats just normal behaviour for people in general.
