The article discusses the potential of generative AI tools, such as ChatGPT, in language learning and travel. The writer spent a month practicing Japanese with ChatGPT's Advanced Voice Mode before traveling to Tokyo and shares their experiences. While ChatGPT was helpful in learning basic travel phrases, it had limitations, such as lacking human-like conversations and providing bland interactions.
