The "mouth-lip" track is basically coming to an end. Some time ago, I predicted this outcome with my friends. To put it simply, there are too many AI auto-reply projects, with varying quality, and the entire track has been overplayed. I also wanted to try these kinds of tools, initially planning to experience them firsthand, but after a deeper understanding, I decided against it—honestly, the usage logic of these products is too complicated, and the barrier for newcomers is quite high. More importantly, when everyone is using similar solutions, the novelty wears off, let alone any competitive advantage. From early expectations to now cooling down, the journey through the "mouth-lip" track really reflects the rapid rotation of hot topics in the crypto market.
