Recently, I can clearly feel the return of the AI concept, possibly driven by Spark. These days, while scanning new projects, I've seen many narratives centered around the AI concept. If AI is really going to make a wave, what should we pay attention to? First, we should focus on the popularity of Spark and related narratives like 'littleguy', which can serve as an emotional indicator for the AI concept. Additionally, the daily new AI projects are also favored by hot money.
