If today computer doesn't exists

Assalamualaikum...hhmmm...it is hard to answer the question..If computer doesn't exists today, i think people have to increase their work time because computer help people do work as faster as it can...but...as far as i know,computer just help in typing more faster and if computer doesn't exists people still can do thier work with type writer...plus computer is quite expensive than type writer...but i didn't say that i agree if we still use type writer because type writer is noisy and quite hard to use it...everybody can't deny that computer is not important because computer is very3 important even i'm not too good in use of computer...with computer we can do our work more faster and efficient...Not like type writer,if we do a mistake,we can't erase it but we need to use other paper to replace it...its somethings like waste...that's my opinion la but i don't know u agree or not with my opinion...that's all...thankzzz... Assalamualaikum....
