Out of all of the millions of things in the world that I would want to change my top choice would be smart computers. I like how we can say things to our phones and the words will pop up n the screen. Technology has evolved so much that we can commnd our  phones to do things that we wish. I hate writing papers, if i could change one thing about smart computers it would be to have the ability to speak out your paper while the computer types it for you.
