Baryogenesis is a field in which we know some things very well but can only speculate about others. It is a field that still has room for growth.
We can be almost certain that there is a matter excess in the universe. This puzzling excess, which is quite resistant to efforts to argue it out of existence, compels us to search for a mechanism that brought the excess into existence. The matter excess is a nagging questing demanding an answer.
We know what conditions proposed baryogenesis mechanisms have to fulfill; a number of these mechanisms have been proposed. It seems unlikely that standard-model physics can explain the matter excess, although we don't know for sure. There is probably new particle physics behind baryogenesis. This makes it an interesting field not only for cosmologists but also for particle physicists.
Aspects of some of the proposed mechanisms can be experimentally tested in the near future. Baryogenesis mechanisms could thus be elevated from speculation to theory. If that is the case, then baryogenesis is just around the corner from becoming an extremely exciting field -- one that begins with a puzzling question with no answer and ends up with a conclusive answer to a fundamental question. That is the optimistic scenario for baryogenesis. The pessimistic scenario is that the relevant physics occurs at some extremely high energy scale, that the proposed mechanisms all solve the problem they were designed to solve but resist attempts at experimental verification. In the coming decade we will find out which scenario applies.
