Obviously that won&amp;#x27;t work for babies, because babies get bored quickly looking at text. AIs can be forced to read billions of words in mere hours!&lt;p&gt;Look at word2vec. By using simple dimensionality reduction on the frequency that words that occur near to each other in news articles, it can learn really interesting things about the meaning of words. The famous example is the vector &amp;quot;king&amp;quot; minus the vector for &amp;quot;man&amp;quot; plus &amp;quot;woman&amp;quot; equals &amp;quot;queen&amp;quot;. It&amp;#x27;s learning the meaning of words, and the relationships between them.&lt;p&gt;Recurrent NNs, using similar techniques, but with much more complexity, can learn to predict the next word in a sentence very well. They can learn to write responses that are almost indistinguishable from humans. And it&amp;#x27;s incredible this works at all, given RNNs have only a few thousand neurons at most, and a few days of training, compared to humans&amp;#x27; billions of neurons trained over a lifetime.&lt;p&gt;All of the information of our world is contained in text. Humans have produced billions of books, papers, articles, and internet comments. Billions of times more information than any human could read in their entire lifetime. Any information you can imagine is contained in text somewhere. I don&amp;#x27;t think it&amp;#x27;s necessary for AIs to be able to see, or interact with the world in any way.&lt;p&gt;If you can predict the word a human would say next, with enough accuracy, then you could also produce answers indistinguishable from theirs. Meaning you could pass the Turing test, and perform any language task they could do just as well. So language prediction alone may be sufficient for AGI.&lt;p&gt;This is the theory behind the Hutter Prize, which proposes that predicting (compressing) wikipedia&amp;#x27;s text is a measure of AI progress. The Hutter Prize isn&amp;#x27;t perfect (it&amp;#x27;s only a sample of wikipedia, which is very small compared to all the text humans have produced), but the idea is solid.</text><parent_chain><item><author>erikpukinskis</author><text>No one would ever imagine that locking a baby in a featureless room with a giant stack of books would give them general intelligence.

Although that&amp;#x27;s usually the initial assumption. In the early days of flight most attempts were based on birds, similarly submersible vehicles were based on fish. We know now it&amp;#x27;s better to use propellers. It could be we just haven&amp;#x27;t found what is analogous to a propeller for the AI world.</text><parent_chain><item><author>erikpukinskis</author><text>No one would ever imagine that locking a baby in a featureless room with a giant stack of books would give them general intelligence.
