Assuming equal likelihood of success for product and library. It may feel that way to us but there is a survivability bias embedded in that assumption. I'd hazard a guess and say incremental value add per unit of effort is greater for product development due to the inherent bias developers have for building libraries under the false assumption that a domain can be conquered for good.
