My favorite one lately has been, what if supply chains collapse and grocery stores are empty for weeks/month, causing most people to starve? Or similarly, what if the electrical grid just stops working for some reason, causing the majority of jobs to evaporate overnight (as well as the aforementioned supply chain problems, and a whole host of cascading effects). As a SWE, I recognize that although this career is one of the most valued in our current economy, we're highly dependent on modern infrastructure. Take away certain services, and all our years of coding experience are rendered useless.
