AI progress is not limited at all, it's the fastest moving research field in the world (5x improvement in efficiency / year for training a task to the same precision for the same cost if I recall correctly, far better than Moore's law).
OpenAI is opening the world to AI and helping people just like Google's doing ,,no evil'', Facebook is connecting people. At the point when an organization gets big enough to not keep its original values (being open for OpenAI), it's not better (less altruistic) in ,,making the world a better place'' than any other organization. Competition and having the power of AI distributed in more companies is good though (until they acquire each other).
