00:00If you checked out every book from every library in the world and scanned them,
00:05and then downloaded every single web page on the internet,
00:09you could delete anything that appears more than once and take out any errors.
00:15And you could feed what's left into a computer program.
00:18This program would read all that information,
00:21breaking it down into smaller pieces like letters and words.
00:25Next, it builds a map of these pieces,
00:28making billions of connections between them to see which ones appear together most often.
00:34By measuring the strength of these connections, it would learn how human language works.
00:39So when you give it the first word in a sentence, it could guess what should come next.
00:46Each time it got a word wrong, it would be corrected millions and millions of times.
00:51And when it was good enough at guessing the next word,
00:54you could ask it to write its own texts, correcting it every time it made a mistake
00:59until it finally gave you words that sounded just like a human.
