This is so exciting. I worked in a lab where we were trying to do this, and so I was very aware what a gold rush we were in. I'm so glad to see that it's actually happening.
This is truly a watershed moment in science. This is going to mark a major turning point in cellular medicine from theory to commonplace care. Eventually, this will end the pharma industry's insulin cash cow.
But it's even bigger than that. Because once we can engineer cells that produce a natural product, the next step is to engineer cells that produce synthetic medicines. Antidepressants, birth control, hormones, weight loss drugs, boner pills... The frontier is huge, lucrative, financially disruptive for pharma companies and life changing for patients. This is a big moment in history, and we all need to be fighting harder than ever to end for-profit healthcare. Otherwise we're going to end up with subscription licenses to our own bodies.
