I attended Li Kaifu's talk on 'Artificial Intelligence' at the Bund in 2018. Han Han was also there. Back then, listening to AI felt like hearing Musk talk about sending people to Mars. I even read the books, and it all felt like futuristic sci-fi. I couldn’t understand it, and it felt like a distant future. Who would’ve thought that just four years later, ChatGPT arrived, and the era of artificial intelligence is now unstoppable.
