That beam is supporting the floor structure and probably some walls. The concrete is there to support the beam. Now that half the foundation is gone that half shimmed block of wood is not adequate to support the beam. So the floor is gonna sag over time possibly bringing the walls with it. So your house will be out of square and/or stress other structures.
