Do Internet actually making as dumber?

We depend on computer to ease us. Seriously,in my opinion,without internet,we will 'die' .We need to use internet to do important things,e.g : online shopping,doing assignments and lots more.A study shows that our memory is affected by internet.Read it more here. I don't think the world could sustain its population level  without the services computers provide.Etc,we depend the internet to buy our flight tickets

In conclusion,the only disadvantage of using too much computer will decrease the communication between people because this causes you to be dumber as you seldom talk with people surrounding you.
