Truth is, Occam's razor still holds: at some point you decide to stop testing and trust that the simplest hypothesis is the valid one. For example, I didn't test 1, -2, 3 which could have invalidated a slightly more complex rule (ie. The magnitude of the number always increases), but at that point I was confident enough the simple rule was good. There is no guaranteed way to infer the rule of a blackbox, but unless you're faced with at least one "no" Occam's razor says you should guess "all sequences are valid".
Maybe he was pouring one out for a fallen comrade?

"There is no longer any doubt: We are entering a mass extinction that threatens humanity's existence.
That is the bad news at the center of a new study by a group of scientists including Paul Ehrlich, the Bing Professor of Population Studies in biology and a senior fellow at the Stanford Woods Institute for the Environment. Ehrlich and his co-authors call for fast action to conserve threatened species, populations and habitat, but warn that the window of opportunity is rapidly closing.
"[The study] shows without any significant doubt that we are now entering the sixth great mass extinction event," Ehrlich said.
Although most well known for his positions on human population, Ehrlich has done extensive work on extinctions going back to his 1981 book, Extinction: The Causes and Consequences of the Disappearance of Species. He has long tied his work on coevolution, on racial, gender and economic justice, and on nuclear winter with the issue of wildlife populations and species loss.
There is general agreement among scientists that extinction rates have reached levels unparalleled since the dinosaurs died out 66 million years ago. However, some have challenged the theory, believing earlier estimates rested on assumptions that overestimated the crisis.
The new study, published in the journal Science Advances, shows that even with extremely conservative estimates, species are disappearing up to about 100 times faster than the normal rate between mass extinctions, known as the background rate.
"If it is allowed to continue, life would take many millions of years to recover, and our species itself would likely disappear early on," said lead author Gerardo Ceballos of the Universidad Autónoma de México."
"Hope for the future
Despite the gloomy outlook, there is a meaningful way forward, according to Ehrlich and his colleagues. "Avoiding a true sixth mass extinction will require rapid, greatly intensified efforts to conserve already threatened species, and to alleviate pressures on their populations - notably habitat loss, over-exploitation for economic gain and climate change," the study's authors write.
In the meantime, the researchers hope their work will inform conservation efforts, the maintenance of ecosystem services and public policy."
