When you can reliably determine whether science has stalled then this argument isn’t relevant. Some might disagree on that. I point out that in absence of evidence of science stalling or not we can’t rely on current engineering output as a proxy. That’s all.
Yes, and..? I am not sure what point are you making.
That we have only tentative evidence that science hasn’t stalled from engineering productiveness.
Why would you care about that when you can go and look at science directly, without trying to proxy it with engineering success?
