I haven’t spent billions on it, so it is not a bad ROI for me. Perhaps it is for those who has invested in creating OpenAI, LLama etc, I am not one of them.

Spending the same amount of money to create a better world would be ideal. But if the money was not spent on AI development does not mean that it would be spent on anything better. That is also a discussion about the money spent on AI and if it has been worth it (a discussion very much wroth having), it does not diminish the usefulness of AIs.
