Even with the algorithmic challenges, games and graphics, and most AI at the moment is short lived and in my opinion easier, because you can deprecate things quicker. A lot of the foundations of what your building on in those fields is rapidly changing and many of the products are built for a single purpose. That makes things easier because you can escape bad choices quickly. On the other hand if you're building a service for a business, like an auth layer or a payment system, the mistakes you make will live on and on and on. And usually you only get one shot at creation before it's in support for a very long time. But to be a good at programming/developer. I would say know enough too know what questions to ask and make sure you talk with people on the client side often. Focus on whats important to them, and get change management and security onside before going near prod.
