Hans Rosling 1, The best stats you've ever seen

TED 2006
Hans Rosling: The best stats you've ever seen (script)
The speaker Hans Rosling stands on the TED stage 10 times. This is the his first talk.  I'm looking forward to reading how his talks will develop in the future.
Summary
Although this talk was spoken 10 years ago, I couldn't feel this old. The speaker says that we are not ignorant but we have preconceived ideas, when we see any data. We want to know what we don't know much. Even policy makers and corporate sectors also want to know for their businesses, thus they are searching many data. However, in fact, the true data which the United Nations, national statistical agencies, universities and also non governmental organizations have are hidden. No public data we now use are taken some nourishment down from it but it was put prices and unnecessary processing. Nowadays, it is no meaning to use the average data of the countries, because there is a lot of difference within countries.
He said that it's not the public's and especially there is no data showed about changing in the world. I think that all of it will be like that. We always see them and algorithms are repeated then we have  prejudiced thinking.
In our world, the Internet is coming. The number of Internet users is going up and it will help the economy of the countries. He works to open public data and to connect between its data and design to be able to easily use what you want data. If a search function is added and everybody can get it out in the world freely, we will be able to look at many data in completely new ways. The best stats we've ever seen will be shown. The Internet has already come into our world. Unless it should be done, the world problem will not be solved. No, no, we can't know true problems also but we can't read the future precisely.
This talk reminded me of Chris Jordan's TED talk: Turning powerful stats into art. In his talk, the data really gave me a shock also.
