Technology from 100 years ago to now has changed drastically. As you showed us we went from a machine only being able to listen to 1 song to having phones that you have access to millions of songs on one small device. In 100 years the technology will be very different. We are making so many advances in technology at this very moment. For instance the Iphone 12 came out the other day, which made even more advancements in phone technology. In 100 years i think there will be flying cars for sure, even more advanced phones and maybe even cars that can transform, just like transformers. Technology will be way different and we are just on the verge of making technology so much different.
