You're right! However, both in this article and a previous article I point out that Euler is the least accurate of the numerical integration methods. I also mention several times that there will be an upcoming article dedicated to exploring other integration techniques. Additionally, in the previous article I mention that the reason we're using Euler's method is because it's the easiest for a student to look at and understand at a glance, not because it's the best or only technique. Finally, other articles mentioned that we are not going through these exercises with game dev or optimization in mind. These are educational articles about physics and physics alone. But as I said, you're right. Anywhere outside of the scope of education, Euler's method is not the best choice.
