Droids
Speaking of R2D2, do droids like he and C3PO actually exist? Well, sort of. Right now, we used robots to do many things for us. In fact, they are often making heavy machinery for us as you read this article. They have effectively taken the need for human labor out of the equation in many factories. They are also helpful for agricultural needs. The question is, would we see any of these droids in space? Technically, we already have.
We have several rovers on Mars right now and we’ve had them on the Moon too. Some robotics have been used to capture images or videos from other planets or moons in our system too. While the Star Wars universe robots or droids might not be completely real today, it is only a matter of time. That is especially true for the military droids you see from the Empire. We already have some military droids, but the “Roger Roger” type is coming. Hopefully, they won’t be as useless.
