Is Web 3.0 still a thing?

Excuse me, but could you elaborate on the current status of Web 3.0? It seems to have been a buzzword for a while, but I'm not sure if it's still considered a relevant concept or if it's just a fleeting trend. Are there any tangible advancements or implementations of Web 3.0 technologies that we can observe in the industry today? Additionally, how do you think Web 3.0 will evolve in the coming years, and what challenges does it face in becoming a widespread reality?
