When someone solves a problem with a thing and you're not that impressed, the best response is "cool" or "learning new things is fun" or, like, nothing. Telling someone they didn't need to do it with that tool is presuming that a) you know why they did it, b) that you are able to judge the suitability for that of that tool for that purpose and under those constraints, and c) that there is no one else who has ever needed to use that exact tool to solve that exact problem under those same constraints.
