GPT-4 is absolutely incredible and even if we never get beyond it the world is a much better place with it than without it. It makes total sense to bet on the team that made this being the best placed people in the world to advance it.
I'm not saying it's not cool tech or that the current level of LLMs don't have some impact, but "the world is so much better" is quite a stretch (unless you are a Nvidia shareholder)
Not to mention the adverse affect of job loss in industries such as customer service almost exclusively hurting people from poorer countries and lower socio economic levels.
