SINGAPORE — When Aniq Hazim was in primary school, his English teacher once gave a lesson about public transport. Looking at the picture of a train on his textbook cover, Aniq uttered: “Siemens C651”, the train's exact model name. 

Surprised, other students and the teacher asked Aniq how he knew about this particular train model. He replied that he had been learning train models and their names on the internet.
