I agree the manufacturing cost of $4,000 doesn't seem unreasonable, but that's the manufacturing cost. The article also states either of these competing treatments would cost insurers half a million $ or more, so it will be much more expensive than today's treatments. Still worth it, but absurdly expensive especially compared to the manufacturing cost.
