Many people, including Elon Musk, have predicted that the year 2026 is definitely the beginning of a new AI era. It didn't bother me at first, but something happened that later changed my mind. Several months ago, I noticed a strange phenomenon that more and more videos which were created by AI were being posted on social media. Some of the videos got a lot of likes. In fact, these videos were just created by AI apps. That is very different from what the influencers did in the last few years. At that time, if someone wanted to create a good video, they needed to use many tools and filmed many things, then edited a video which could express their thoughts well. In 2026, you just need to tell the AI apps what you want to express and wait for a few minutes, and a great video appears in front of you. AI has been deeply changing our lives. It makes me feel that 2020 was a very long time ago, because what we did in 2020 sounds really outdated. Now, I am curious about what our lives will be like in 2030? Will smart phones still exist?
