The ego is the sum of all the memories that a person has accumulated since childhood.
Memories are matter, and they reside in the brain in some form, that is why a head trauma can cause amnesia, which proves the physical existence of memory. In other words, memories are dead, they have no life of their own, it is the consciousness that makes them feel alive, but otherwise memories are dead matter.
By that logic, if memories are dead matter and ego is the sum of memories, then it follows that ego is dead matter.
Now you know why you should not rely on your ego.
Everything that you know and believe is dead matter. Unless you see the fact of that, you're a slave to the dead matter, which is your ego.
