We don't really have a place for economic articles, and we also don't really have a place for sharing links easily. So I'll just drop this here and hope people see it. This is an excellent long-form article from Medium that really got me thinking about economics, currency, and sci-fi novels. Honestly, the author raises more questions than he answers, but his overview of money and currency is awesome, and really applicable to writers.
The Economics of Star TrekAnyways, enjoy

Any time I come across interesting articles I always try to get them around -- it's good to get outside sources and keeps an echo chamber from forming

Let me know what you guys think of this -- I'd love to discuss it.
