It's just been half a month of rest, and when I came back, I was almost unable to keep up with the pace of AI iteration. I still remember the first time I used ChatGPT five years ago; at that time, only a few people were involved in AI, and I only saw it as an enhanced search engine and a tool to improve essay writing efficiency. But AI development has never been a linear progression; it's an exponential explosion: from text generation, to image creation, to real-time multimodal voice interaction, and one-click generation of 15-second short videos.
