Pretty adequate concept for their age. Targets of comparable time didn't had much armor, so there were no need in one big gun, but chassis allowed to carry much more weight. Only after first years of war, when tanks became more armored, big gun became required and having more that one became impossible. Multi-weapon concept didn't really died, for example, IS-7 had 8 machineguns, few facing back. Modern BMOP/BMPT is a good example of classic infantry tank with multiple main weapons.

Multi-turret tanks just arrived too early, I guess we'll see more of these vehicles in future, when automatization will allow to use more guns with few crew.
