I am a lot more pessimistic about the startup scene in this area.
Look how ChatGPT can teach languages[1], good luck building an AI powered language learning app…
It gets worse for startups because Google and OpenAI have a ton more context about me. For example in the language learning conversation Google can refer to my spoken samples from other places to improve the experience. And yet, no PM at Google needs to think of this, they only need to hook up the data and throw more compute at their models.
