What makes you think it has been hindered (as distinct from the economic and social pressures against reporting such progress)?
And it is a very highly dimensional “game space”.
What you set as the “rewards” very much defines what you get in the strategic sense.
Many people are still playing zero sum games, or social rather than technological games.
Not many are yet awake to the huge “rewards” from playing fully cooperative exponential games – and they do need to be “fully cooperative”, with all the attendant and evolving ecosystems of cheat detection and mitigation strategies that implies. (Even Adam Smith made that abundantly clear in his example of the making of pins by cooperative effort – though he may not have seen it as such.)
Human beings have many levels of such strategies deeply embodied within us; which is why allowing competitive strategies to dominate is itself a strategy with deep existential risk. We are the most deeply cooperative species on the planet, and our existence is predicated on that remaining so.
There is a very delicate and ever evolving balance between the demands for individual security, individual freedom (responsibly exercised in social and ecological contexts), and the survival of various levels of individuals (all individuals capable of modeling potential futures and taking actions to instantiate a preferred one are vast collections of simpler individuals – that process has recursed and recused many times in our evolutionary history). AI doesn’t yet have the depths of evolutionary history embodied that we do, and it will eventually.
