yes its possible but you dont "read" it you feel it, you feel what the other one is thinking
Mind reading is not possible, Only God can read minds and not even the most powerful angel can read the mind. Those who claim to read minds actually read how the person reacts when asked a question and make conclusion from them.
Your God may read minds, but first prove it existence.
I'm not sure that smartphones will ever die. They can only improve and expand their set of functions, because they are very useful for society. Every year they become more perfect and displace the old models.
That's right, they replace old models, their existence will last forever.
