I think that computer will change in the future not alot but maybe a little maybe they have faster speed. And also maybe you wont even have to type or move the mouse maybe you would be able to talk to the computer and it would do the things for you.The computers back then were thoes ugly ones with the big thing on the back and now they are with flat screan and they are faster and back then they were really slow almost like the ones we have in the clasrooms.

A life without a computer was probably difficult back in the old days because you had to go top the libary and get your research fron book and know you dont have to do that you could just turn your computer on and search it up in the internet. i wouldnt like to live in the old days because there was bearly tecnology. I imagine the computers relly cool in 30 years fron the future they would probably would be easier to use.
