I think companies are moving too quickly with AI and LLMs in particular. I think that the data LLMs are trained on should be very well-known - not just sanitized and certainly not just trained on the "whole web". GPT-4 is unwieldy... it's incredibly powerful but is still unpredictable and has learned how many "bad patterns", so to speak, that we'll never know since its basically a giant black box.
The ChatGPT version is the least harmful in my opinion; sinister are the propagated problems when GPT is utilized under-the-hood as a component in services (such as Bing search).
