I think that superior technology advanced aliens would have their own asi so if one day our asi get detected by a alien I don’t that they would want our asi they probably just want to know how advanced our asi is it like when we go to zoo if we see a monkey using a rock as a tool to use in their daily lives we wouldn’t take a rock from a monkey and risk getting hurt by a angry monkey but we probably just want to know what else they use and how they use it
