The amount of time to build something like this seems like it would offset the amount of effort it would take just to write good character dialogue. AI tools are basically word calculators, which means you have to provide data for the LLM, which means time to produce this data, time to build guardrails, etc. Even in this implementation, they say they had to build guardrails so that they don't say anything "harmful."

There are also a number of lawsuits going on that will set a precedent for how training data can be utilized in commercial products. While I expect them to take the side of large corporations with vast resources at the expense of ethics, there's the possibility that they will do the right thing. This will affect how AI tools wil be used in such contexts.
