What technology seems like science fiction but is actually real? What technology do you think is the coolest?
I'm always interested in new technology, and I'm always surprised by how much technology seems like science fiction but is actually real. For example, I recently learned about a new type of battery that can be charged in seconds and lasts for days. I also heard about a new type of material that is almost impossible to break.
I think the coolest technology is the stuff that we can't even imagine. I'm always amazed by the things that scientists and engineers are able to create.
