Vinton Cerf is literally the father of the Internet (the co-father to be absolutely precise.)
In this talk at Google's office in Zurich Switzerland, he describes how the Internet came to be created and what the network was like on Day One in 1969.
More important Cerf applies his 39 years of experience and insight to anticipating where the Internet is headed.
The Internet has a lot more growing to do and if you plan to be part of the Internet for some time to come, it makes sense to listen to what Cerf has to say about the technology's future.
