I don't think it will be rendered valueless, but it shouldn't be completely exclusive. Basically as an extension of today's search model (which is a large part of what LLMs are, along with a grab-bag of useful ML algorithms), people should be able to access information universally, but if they want to go to perspectives or very fine details, then a pay model is acceptable, as long as there's a trail from freely available information and evaluable models. Ultimately imo there are bigger problems with elite/gatekeepered information than finding new ways to produce or support information development, given the power a few corporations are gaining and the opportunity to overcome stratified society.
