The mechanics of torpedo guidance and control are fascinating too. With nothing but a pendulum, a hydrostat, and some clever linkages, torpedoes were able to manage their depth over 100 years ago. In WWII the same mechanism was refined to maintain depth with an accuracy of just 6 inches. A radio controlled boat might as well be a step backwards in comparison.
don't be so negative, I'm sure someone made a ton of money pretending those use Blockchain or Machine Learning.
