"Ever" is a long time, but I don't think we will solve economics as it is defined today. Maybe if we reframe the problem somehow, and in the process change the way society deals with money and allocation of resources.

Another problem is that if it was "solved", who gets rich or poor would be predetermined and probably could be changed as we want. How could that work? Who would accept a system where the results of a lifetime of work are fixed and you cannot change them? Communism had a big problem with this, nobody bothered to do a good job at work, because it made no difference to your income or status or anything like that.
