Some investors won't get their money back, and some people will lose their jobs.
In the economy, the difference between winners and losers in terms of assets/resources may get larger. By far, HN readers are better positioned to gain than others.
But the biggest question is the new disconnect between a healthy economy and well-being, as the economy soars but people suffer. Goodwill underlies all economic activity (now and historically), and without goodwill opportunity and value of all kinds will mostly be destroyed.
I wouldn't call this dead economy. Cultures and economies will become tribal, with private adjudication and governance, to create pockets of relative goodwill.
