"You don't see radio changing gradually and suddenly become radar. #Darwin's theory doesn't work for #technology, and we have to make a new observation."

"Novel technologies are constructed from existing technologies. These offer themselves as components for the construction of further technologies."

- W Brian Arthur at SFI today

Unlike the two-parent #inheritance typical to (but not ubiquitous among) #complex organisms, #technology inherits features from n parents - a "vast ancestral #network" more like horizontal gene transfer networks in #bacteria.

W Brian Arthur on sumulating #invention on a chip:
Does #Archaeology support the Theory of the #AdjacentPossible - that #innovation is combinatorial, persistent, cumulative?

In short, yes. SFI's Tim Kohler on the #Paleolithic data of #technology #evolution & the #prehistory of the infamous "hockeystick" curve:

😉 @SAPIENS_org
#Economist Roger Koppl of @SyracuseU presents a model for the #AdjacentPossible at SFI.

Output = "a combinatorial explosion" or #singularity, albeit one that arguably occurred millions of years ago, or in the distant future (since the model doesn't specify t = 0):
"We can't have universal models if organisms differ. But most of our models are universal. So how do our models need to differ for species-specific #search?"

- @toppofelin (@UniofOxford) reminds listeners at SFI today that we live in worlds, plural:
#umwelt #suchbild #affordance
"Irreversible #systems flow to these tricky systems you could mistake for a reversible system."

Lee Smolin of @Perimeter on how #complexsystems thinking inspired a heresy in fundamental #physics: that #time #symmetry in familiar laws is #emergent from deeper, asymmetrical laws:
Classical #physics has failed to offer adequate #economics models. Could #QuantumPhysics succeed in supplying useful analogies for modeling the ontic #uncertainty & #disequilibrium of the #economy?

Naresh Singh at SFI today:
Theorizing the #AdjacentPossible in evolutionary systems, Walter Fontana of @Harvard suggests a mechanism for The Baldwin Effect at the intersection of genetic plasticity and mutation.

Evolvability points to a link between the non-hereditary and the hereditary, without Lamarck:
"The legal system becomes more complex as strategies & precedents proliferate in a combinatorial explosion that was not pre-statable."
"While we cannot control precisely how the law develops, we *can* enable the development of the law..."
- Attorney Caryn Devins Strickland at SFI
Can we make in silico patients? Yes:

@colinhill1, founder of @gnshealthcare, on building the Holy Grail of #medical modeling: the patient-on-a-chip.

Here the model shows a responding & a non-responding population to #stemcell therapy, validated by empirical #data:

#myeloma
"Understanding #wellness is the key to understanding #disease."

Lee Hood (@isbsci) on the importance of an #integrative #complexsystems view - #networks, #hierarchy, #holism, #nonlinear dynamics, #signal-to-#noise issues, & deep phenotyping - to 21st Century #medicine:
The drugs don't work: Lee Hood of @isbsci on the problem (highest-grossing one-size-fits-all #pharmaceuticals work for ~5%) & solution (personalized #medicine informed by a #complexsystems approach - including #nutrigenomics, #quantifiedself, #microbiome tracking, etc.)
"A totally new approach to biomarker discovery & drug delivery discovery."

"For many diseases, your genetic risk is going to determine how you get treated."

Lee Hood of @isbsci at SFI on a multi-omics approach to teasing apart complex correlations for innovative #medicine:
A fate worse than #death: ~2/3 surveyed said they'd rather accept an #obesity intervention w/ higher mortality rates than one that would forbid sweets (pic 4).

Yet patient preference gets ignored, leading to clashes between #healthcare companies & regulators.

Bennett Levitan:
"Models aren't just used to predict things; it's how people present their worldviews to one another."

- Stephen Guerin @redfishgroup at SFI on #ABM & #photogrammetry for #forestfire modeling/fighting with @Simtable

#sousveillance #design
"Can we beat the software designers to #AI with chemical systems?”

- @leecronin (@UofGlasgow) on de novo #biology (aka "#chemistry with a #history") & the inspiration behind mapping #selforganization w/ "pathway assembly" to ask: created, or evolved?

#kolmogorov #entropy #OoL
"The origin of life was almost certainly inorganic."

#Autocatalysis in an inorganic salt: complex networks of self-replicating molecules in the @leecronin lab at @UofGlasgow:

#OoL #chemistry #biology #selforganization
