Dang. My kids are just getting the hang of using ChatGPT as a way to generate random quizzes and additional homework problems; to the point where both of them just automatically use the AI to "fill in the gaps" each evening. (Prior to AI, additional HW was met with less enthusiasm than you'd think!) I told my wife that the billionaire class spent the last few decades cheating the tax system (and, thus, the education system) just to weirdly dump a trillion dollars into the AI ecosystem to build the world's finest tutors. I really hope that doesn't Go Away™.
Even if OpenAI folds, the open source stuff is good enough that someone will build a compelling tutor platform in their place. It probably already exists.
Don't worry about this. There's no way these tools are going away. If this bubble bursts it may wipe out the incentive to continue this frenzied race to build novel AI, but ChatGPT et al won't be shut down, and even if they were, the open-source LLMs comparable to the cutting-edge of 6 months ago will still be online and available. Plus, even if AI progress froze solid tomorrow, I think it would take decades before we'd start to anywhere-near-saturate the potential space of applications & use cases to really do the current tech level justice. (Also, even post-bubble, AI progress would not freeze solid, to put it mildly)
