what if computers are not invented?

it will be a big headache for all business industry if computer is not invented, everything will be snail pace and no much progress will happen..

I am glad that I am the first one ~! Well,if the computers do not exist,I think I can not answer your question firstly.Without computers,we just can play the paper games but not the computer games.Of course,the scientists also need to calculate a huge number by themselves!!! It's so amazing!Right??!!The social development will not be so rapid,because we need cellphone ,letters...to communicate with each other. And i think if the computer was not invented,another thing will be invented to take the place of computer,maybe "putercom"~?!!!HAHA~
