The other view is that simplicity (physics) is actually just a subset of complexity (like the study of biology and systems science). Complexity may be the more general, the more fundamental, because that is the way the world actually is - in a developed state.
A classic cite here is from Schrodinger's What is Life?
“living matters, while not eluding the ‘laws of physics’ as established up to date, is likely to involve ‘other laws of physics’ hitherto unknown, which, however, once they have been revealed, will form just as integral a part of science as the former”.
Then even more bold is Robert Rosen. Here is a summary from The Way of the Cell: Molecules, Organisms and the Order of Life by Franklin Harold.
“[Rosen's] quest for principles that make organic systems different from inorganic ones does not lead him to invoke mysterious forces that breathe life into the common clay, but he does bid us to rethink the relationship between biology and physics, and that is quite radical enough. Both disciplines deal with systems, and for the past two centuries biologists have sought to interpret their subject by the extension of laws inferred by physicists from the study of simple mechanisms. That, in Rosen’s view, puts the cart before the horses: in reality, simple systems such as gases or planetary orbits are special and limited instances, while complex systems represent the general case. If organisms are ever to be understood as material physical entities, physics will first have to be transformed into a science of complex systems”.
Where does the future of fundamental physics lie? Perhaps in the principles of systems already uncovered by theoretical biology.
We are of course seeing the likes of Smolin picking up selection theory to talk about Darwinian cosmology.
Which is nice, but that bit of insight is what, 150 years old? Cutting edge stuff in theoretical biology is semiotics, or evo-devo, or dissipative structure theory.
(I should give an honorable mention to cosmologists like Charley Lineweaver who are using current concepts -
