I think the speech was a bit timid about the subject.
The web originally came about as a place for the free exchange of ideas. Many companies that gave birth are no longer around or play a very minor role in how people use it.
He failed to take on the biggest problem of the net today - the threat to freedom of speech and ideas by a nameless cadre of people or algorithms that delete "unacceptable" subjects.
We learn of people being denied access to Facebook or being banned from posting (I am one of them.) We know that Tweets are deleted for unknown reasons. Redditt has a cadre of the most extreme leftist moderators on the face of the planet.
There is also a web that few even know about - The Dark Web. How many here have accessed it? Even know how big it is.
Technology is giving billions the tools to learn and improve their lives.
How much of that is being censored by government and private companies?
