I would probably wait and see how the situation settles, as a majority of employees is now urging the board to reverse its decision. But even if they oust Altmann and move towards "ClosedAI", there are many alternatives to ChatGPT already on the market (Bard, BingChat) as well as open source alternatives (Llama models, OpenAssistant...). So overall in the grand scheme I dont think much would change for LLM research.
