A domain expert or becoming one is what makes a startup profitable. What is an expert: Someone or something recognized as such by other recognized experts and trusted by a significant number of those who are not. What is a domain: A limited area of human knowledge small enough that it can fit in one person's memory but wide enough that when applied it solves multiple useful problems. How do I become a domain expert: By doing. First learning. Then making. Finally advancing. Unless of course you are creating a new domain which skips to step 3. Am I an expert at something I take for granted: No. Most US adults know how to drive and do it semi-(un?)consciously. They are not expert drivers.
