That's the catch, yes. All other things are very rarely equal. There are almost always other factors worth paying attention to when forming a long-term strategy. A handful that spring to mind are availability of talent, software runtime performance, schedule impact of static vs dynamic typing, and expected runway of the business. Producing a statically typed system that runs slowly and correctly after the business has folded is not always more valuable than producing a buggy one in time to start producing revenue.
