Can ChatGPT Learn Chinese or Swahili?

The English-speaking world was rocked by the advent of ChatGPT in November 2022. Here, suddenly, was a chatbot that could do a credible imitation of a human being, producing text that seemed like it was written by a real person. People worried that ChatGPT, Google's Bard, and the like would cause widespread cheating as students turned over their writing assignments to a machine, or that they would lead to the mass production of misinformation and propaganda, outstripping the abilities of Russian troll farms. Those concerns arise in languages other than English as well. So far, however, chatbots based on Large Language Models (LLMs) appear to perform best in English, while sometimes struggling to mimic humans in other tongues.
