Hi, I am currently an undergrad student exploring different fields of engineering. I find that there are so many fields to choose from, it is as much astonishing as it is bewildering. What I would like to do is work on building the technologies of the future. Specifically, I am interested in designing and creating gadgets that have never been made before. Such as, a gadget that would enable a human being to have an exoskeleton of protection or a gadget enabling a human being to fly. I understand these types of creations may not become a thing reality for a long time, but I long to be on the leading edge of their upbringing. If someone could please advise me on the best types of engineering to study to prepare for entry into this line of work, I would greatly appreciate it.
