You wouldn’t go wrong with electrical engineering if this is the stuff you like. However, I think most engineering and engineering-adjacent disciplines (basically STEM) will give you a similar set of tools to approach any problem. If what youre really after is the pioneering aspects of his work, consider a double degree in business/engineering. The problems businesses face are really just engineering problems in disguise. Since most people who have the desire and capability to be an engineer become engineers instead of businesspeople, there’s a dearth of engineering talent in most non-engineer roles. In my last role at a Fortune 500, my nickname was “The Wizard” because I was so good at translating business needs to computer workflows it seemed like magic to my coworkers. When I’d regale my successes to my engineer friends they’d just laugh. At my org, I was 1 of 1 who could solve these problems. At their firms, my friends were on teams of 20+ who could all do what I did in their sleep. They worked in a more competitive domain where magic was an every day occurrence, so their work product felt lackluster when compared to their peers.
