So it will go from generating toy code that usually compiles, to being able to one day reliably solve day 1 advent of code brain teasers, to generating useful software? Is there domain limitation to this growth and performance? Medicine, theoretical physics, art, engineering, pure/applied maths, etc.? I don't see how you guys are getting this from the current tech? Maybe there is an educational resource someone can suggest?
