Many people's estimate of the probability-weighted impact OpenAI will have is much greater than anything that I'd ever call a Pascal's Wager. You may disagree, but a lot of us actually have our expectations somewhat quantified and grounded, which is very different from the argument as applied to religion.
Personally, I think there's a greater than 10% chance that we'll see AGI that definitively surpasses human ability within the next 50-100 years (growing a lot higher as we get near/past 100). And given what's coming out this early on with minimal funding, I expect that the work that OpenAI does in the near future will have at least a 10% chance of strongly influencing the direction of that AGI work during the critical turning points. A 1% or more chance of their work mattering a lot is plain old betting-on-a-black-swan territory, not Pascal's Wager.
Well put. The Open Philanthropy folks take a broadly similar view of the probabilities, both of when strong AI is likely to arrive and of how much positive influence per dollar they can have on how things turn out:
