I don't think software engineering is ever going to be solved, but financial analysis will definitely never be solved. It's impossible, the nature of it dictates that, whatever changes happen will further change the results. Financial analysis requires novel thinking, and even if you have AGI that can engage in novel thought they will just be another input into the system.

Just like AI, the winners will (continue to) be the ones with the most access to data and the technical and financial capital to make use of it.
