oh it is on
Americans invented the ARPANET, the military forerunner to the Internet
Tim berners lee invented the WWW as I said, the hyperlinks and websites that actually make up a large part of the internet today, without which it would just be another network
The term computer could be argued as to have been created by any number of people, it just depends how anal you want to be, in this case I would cite charles babbage glitter, who created his computer when america had only barely been founded, before taking it to differential engine world and getting caught for having kiddie porn in the gears.
America existed on a policy of isolationism for a large part of the last century, very few countries could have done that or still could do it today, America is abundant with natural resources and is conveniently located in such a way that have allowed it to flourish in a fraction of the time it has taken other countries. No country is founded by 'smarts' that doesnt even make sense.
