There is a case to be made for specialist programmers. It would be cool to find an expert exchange where highly specialized folks can market their highly specialized skills and get paid for very specific tasks.
I’ve faced an issue at work where we’ve needed help with an open-source library/framework and needed more support than StackOverflow / GitHub issues. The company was willing to pay in the hundreds of dollars to get an expert to intervene.
A niche market place (like UpWork but much simpler) where developers can get paid to tackle problems that are very specific to them. The client would post a well-defined problem (with IP filtered out), and the specialist can solve them as a customer service agent would solve a support ticket. An HIT platform like Mechanical Turk but specialized for small programming tasks.
