I think we also need to ask experts in what? In our work we often quote research which shows that experts perform poorly in forecasting change, precisely because they are experts in a narrow and closed way - long history of deep training in a specific subject. Maybe the new expert is one that can take all the training and be flexible in their mental models to facilitate the collaboration that is both desired and needed in the sorts of examples talked about here - medical cases for example. In a complex medical situation I would not want a rigid medical expert or a crowdsourced solution. But a medical expert with great social and collaboration skills using others in the process would be fantastic.
