An eight-year-old boy who became the world's youngest coder has set his sights on building a robot doctor. Kautilya Katariya, who set a world record for being the youngest qualified computer programmer two years ago, recently achieved grade nine in GCSE maths, the highest possible mark. Katariya, from Northampton, has already developed AI software and one day hopes to set up his own company. The Year 3 pupil taught himself coding during the Covid-19 lockdowns and prepared for his GCSE exams alongside students in Year 10 and 11. Rather than playing computer games, he has more fun building them using programming languages such as Python.
