I think that is GP commenter's point. If LLMs were to outperform humans in this area, such that anyone could produce a highly marketable pitch deck for any given business idea, then better PR would no longer provide a competitive edge with regards to getting funding, and would thus no longer be a critical skill in the free market. This could be a net positive, as whatever criterion investors may start using to decide which businesses to finance, at least it would no longer be a proxy of 'which startup had enough money to hire the best PR staff to sell their idea'.
