Even gravity has exceptions—yes, really, this is a standard topic in philosophy of science because the Laws Of Gravity are so clear, yet in practice they are riddled with exceptions and errors
In addition to what the others said on this thread, I’d like to say that my main problem was with the author’s attitude, not the accuracy of his proposed law—though the fact that it apparently has glaring holes in it doesn’t really help. When you discover that your law has huge exceptions (such as f.ex. “all crustaceans” or “Mercury”), the thing to do is to postulate hidden planets, or discover relativity, or introduce a term representing dark energy, or something. The thing not to do is to say, “oh well, every law has exceptions, this is good enough for me, case closed ! Let’s pretend that crustaceans don’t exist, we’re done”.
And we’re talking about real-world statistics: has there ever been a sociology, economics, or biological allometry paper where every single data point was predicted perfectly without any error whatsoever?
I’m not sure what you’re referring to; of course, no one expects any line to have a correlation of 1.0 at all times. That’d be silly. However, it is almost equally as silly to take a few data points, and extrapolate them far into the future without any concern for what you’re doing. Ultimately, you can draw a straight line through any two points, but that doesn’t mean that a child will be over 5m tall at age 20 just because he grew 25cm in a year.
Absolutely; if you measure in certain ways, diminishing returns has clearly set in for humanity. And yet, compared to hunter-gatherers, we might as well be a Singularity.
How so ? Perhaps more importantly, if “diminishing returns has clearly set in for humanity” as you say, then what does that tell you for our prospects of bringing about the actual Singularity ?

Well, that’s useful advice to the Newtonians, alright - ‘hey guys, why did you let the Mercury anomaly linger for decades/centuries? All you had to do was invent relativity! Just ask Bugmaster!’
I wasn’t aware West had retired and was eagerly awaiting his Nobel phone call.

Why do you think the existing dataset is analogous to your silly example?

There’s a difference between acknowledging the problems with your “fundamental law” (once they become apparent, of course) but failing to fix them for “decades/centuries”; vs. boldly ignoring them because “all laws have exceptions, them’s the breaks”. It’s possible that West is not doing the latter, but the article does imply that this is the case.

Which dataset are you talking about ? If you mean, the growth of cities, then see below.

Not much.
Why not ? If humanity’s productive output has recently (relatively speaking) reached the point of diminishing returns, then a). we can no longer extrapolate the growth of productivity in cities by assuming past trends would continue indefinitely, and b). this does not bode well for the Singularity, which would entail an exponential growth of productivity, free of any diminishing returns.

It didn’t sound like that to me. It sounded like some people had absurd standards for scaling phenomena, and he was rightly dismissing them.

There’s nothing recently about it. Diminishing returns is a pretty general phenomenon which happens in most periods; Tainter documents examples in many ancient settings, and we can find data sets suggesting diminishing returns in the West from long ago. For example, IIRC Murray finds that once you adjust for population growth, scientific achievement has been falling since the 1890s or so.

It doesn’t bode much of anything; I referred to you my list of ‘what diminishing returns does not imply’ for a reason: #1-4 are directly relevant. Diminishing returns does not mean no exponential growth; it does not mean no regime changes, massive accomplishments, breakthroughs, or technologies. It just means diminishing returns; it’s just an observation about one unit of input turning into units of output as compared to the previous unit of input and outputs, nothing more and nothing less.
This is obvious if you take Tainter or Murray or any of the results showing any diminishing returns in the past centuries, since those are precisely the centuries in which humanity has done the most extraordinarily well! One could say, with equal justice, that ‘this does not bode well’ for the 20th century; one could say with equal justice in 1950 that diminishing returns bodes poorly for the computer industry because not only are chip fab prices keeping on increasing (‘Moore’s second law’), computing power is visibly suffering diminishing returns as it is applied to more and more worthless problems—where once it was used on problems of vital national value (crucial to the survival of the free world and all that is good) worth billions such as artillery tables and H-bomb simulations, now it was being wasted on grad students and businesses.
