No, but I am suggesting that OpenAI and Anthropic are further down the RSI path than any of the other companies, as we can see from the model that solved Navier-Stokes being less than two weeks old at the time: https://openai.com/index/navier-stokes-solution/
If four other labs are six months behind, it really doesn't matter in the long term: in six months, they'll all have these capabilities. Time does not stop moving forward! We haven't seen real moats aside from capital in this space, and even the effect of capital seems to only give a thin, easily eroded edge.
I think the point is that RSI is meant to lead to exponential growth in capabilities. If that comes, then being 6 months behind leads to a greater and greater gap, because of how exponential growth works.
Personally I expect there is some initial gap on new capabilities as they are released, and then it closes quickly. Astra is good at math and 3d modelling, this will come soon to the others and in 6 months we'll be able to run it quantised on a 3090.
Or the entirety of China. People forget that progress is incremental until it's not. Then some revolutionary insight or capability comes along that disrupts the whole field or market.
Yes, labs with more (human) resources may have a bigger chance at being the first to gain and implement such an insight, but it's not a given that they will.
