My time is spend mostly not on writing code, but thinking what program has to do, testing (including writing unit tests) and understanding errors, I always tell people half joking programming is not about writing code, but an ability to debug it; understanding requirements, errors and bugs is hard, writing code and fixing bugs is relatively easy, in general. Maybe Copilot 2 will do exactly this; it will generate tests based of half working code, run them and suggest improvements, that would increase productivity by like ~100%, but to me this sounds to good to be true.
