Wow, what a misinformation festival. Good luck. Though only a close view in three dimensions can provide sufficient detail to allow an experienced repairperson (not a luthier; luthiers make guitars) to judge how to fix the break. But unless a poor job is done, it will be solid and strong. This kind of break is super-common. Hack jobs look bad and fail; good jobs are very, very strong and stable -- typically, stronger than the original neck wood and grain. People launching strong opinions, not all of them well-informed by personal experience and skill, is natural, but what you need is to hear a diagnosis from a sound sourc e with the guitar in hand.
