There are probably several possible answers to this question – for instance, if we take Elon Musk as an example, through reading. Musk claims to have spent 10 hours a day reading science fiction books as a child – which, for example, explains the idea of self-driving Teslas. But his interest did not include only works describing alternative futures. He is said to have read the entire Encyclopaedia Britannica at the age of nine. Undoubtedly, it is difficult to get by without material knowledge, and he seems to have recognized that even at such a young age.
