Abstract
We show that if the nearly linear time solvers for Laplacian matrices and their generalizations can be extended to solve just slightly larger families of linear systems, then they can be used to quickly solve all systems of linear equations over the reals. This result can be viewed either positively or negatively: either nearly linear time algorithms can be developed for solving all systems of linear equations over the reals, or progress on the families that can be solved in nearly linear time will soon halt.
