Imo, building and flying drones should be a course in high school. They will be extremely valuable in the future. It also teaches great skills about how electronics, servos, ESCs, and transmitters work. Far more valuable than Shakespeare if you ask me... It would be genius to have a group of 100s of thousands or even millions of kids and adults with drones locked away in a secret facility controlled by the airforce that could be utilized in case of emergency war, where they could be summoned and take them off from that location from the comfort of their home set up. It would be incredible and extremely effective, though would perhaps need training and quarterly checks ins online.
