Domain Experts are often not the right people to innovate and disrupt their own domain.
Rethinking overcomplicated systems, processes, industries, and disciplines often requires a fresh pair of eyes, a learner mindset, a willingness to ask "dumb" questions, and excellent craft.

Instead, a) look for craftspeople with incredible taste, judgment, intuition, and process b) pair them up with domain experts, and watch the magic happen.
