Teens 14 to 16 can use it, but only under teacher supervision. Only 17 to 19-year-olds are encouraged to learn it properly, for university and work. The PM's reasoning is simple: Children first need to learn to read, write, and do maths. The fundamentals. Before the shortcuts. I find myself caught in an interesting middle ground with this. One is I totally agree that you only learn by doing things and in general the more stripped back the better. The other is I've seen my son learn more in a 10 minute conversation with AI than reading or studying the old way. Like most things HOW you use it and your overall approach and mindset is what will determine the long standing impact and effect it has.
