I pay for pro max 20x usage and for something that is like even little open ended its not good it doesnt understand the context or edge cases or anything. i will say it writes codes chunks of codes but sometimes errors out and i use opus 4.6 only, not even sonnet but for simple tasks like write a basic crud i.e. the things that happen extremely higly in codebases its perfect. So, i think what will happen is developer get very efficient but problem solving remains with us dirrection remains with us and small implementation is outsourced in small atomic ways, which is good cause who likes boilerplate code writing anyways.
