When I watched the 6-minute video from the article, I immediately thought of a scene from an Avengers movie. In that scene, Tony Stark, also known as Iron Man, works with his technology. He manipulates a floating, transparent screen that he can see through and control with his hands. When I was younger, I remember imagining myself owning the same technology from the movie. I also wondered how many years I would have to wait for that kind of technology to be released, especially since technology keeps evolving so quickly. I almost forgot the article’s main point: technology becomes more meaningful when we can interact with it ourselves, rather than just swiping or looking at it. 
As Bret Victor explains, our hands are meant to feel and handle things, not just tap on a flat surface. I liked the examples he gave about how there is almost nothing in the natural world that we interact with by just sliding. In real life, we do not just slide our hands on things. We hold them, adjust our grip, and feel their weight, which helps us control them better. That kind of interaction is missing when we only slide on a flat screen.
Thinking about it now, even if something like Iron Man’s interface existed, it might still feel limited if it only relied on gestures in the air without any real sense of touch or resistance. This led me to think that even if something looks advanced, it can still miss the deeper idea of creating something that we can fully see, feel, and physically interact with.
