Can you create a game that's 500GB in file size and download that in just 1 second or less?

That’s 500000MB in file size, even if you have the fastest internet connection available: it’ll still consume more than a single second due to the file size. The fastest connection is 1000TBps but that’s not a home connection with a WIFI router: rather from a labratory with a large server or database. Is there a way to expedite internet connection to download games that are even 200GB within less than a fraction of a second?

Like, the moment you click the download button, it immediately finishes downloading regardless of file size. So, put that into perspective: is it even possible to have a internet connection with the capability of downloading steam games that are 250-400GB+ within <1 second upon installing? Usually, they take up half an hour or more inrespective of internet connection speed (not fast enough).
