I don't think that every consequentialist view of ethics reduces to equating morality with maximizing an arbitrary but fixed utility function which leaves no action as morally neutral.

Under bounded resources, I think there is (and I think remains as the horizon expands with the capability of the system) plenty of leeway in the "Pareto front" of actions judged at a given time not to be "likely worse in the long term" than any other action considered.

The trajectory of a system depends on its boundary conditions even if the dynamic is in some sense "convergent", so "convergence" does not exclude control over the particular trajectory.
