Detecting Gamma Ray Bursts

We can barely pick up super bright, very distant gamma ray bursts. But we could also improve our technology and make our gamma ray detectors more sensitive. Then we could see dimmer things that were further away, including gamma ray bursts or alien technology. We certainly should keep an eye on that. There are also other more subtle ways that we might be able to detect nuclear weapons,. explosions on other planets, and to distinguish them from gamma rays.
