I would really like to kill a deer with a selfbow, river cane arrow and stone point. Just not sure I want to invest the time and energy to build that setup.
Or we can go the opposite direction and see how high tech we can go to 'hunt' an animal. Like Zombieland, best/most creative zombie kills....I think Trump Jr is the current award holder by shooting a fenced sheep with a rifle equiped with laser and infrared red scope.
I have a coworker who is very tech savvy. He is able to bring up his home cameras feed from a website he created. He'll press a button that will project his voice on a speaker near the back door that call to his dog. The dog will come to the door. He then press a button that will remotely open the dog door so the dog can go out and pee. it is setup to do this automatically, he was just showing me how he set it up. Time for coding, wireless connection, a Rasberry Pi, a motor, and a scrap pieces from the junkyard. That's all it took.
I saw videos of some guy who attached a handgun to a drone. How long before someone setup a remote turret next to their cell cam?
There is no line except the one we draw and even then, lines in the sands are not permanent.
