Punctuated equilibrium of stalled cultural-evolutionary progress as a side effect of the emergence of accurate AI models. Reminds me ideas of Sergi Valverde @svalver.bsky.social . Could we call it the ultimate imitation regime? When you loose the intellectual wandering. 🧪 www.nber.org/papers/w34910

Thanks for the invitation — a very interesting synthesis. One angle for a commentary could be tinkering under ecological and network constraints, especially in software and technological systems. I’d be happy to contribute from a complex-systems perspective if useful.

As a side point: the term "tinkering" is not even new in the context of cultural evolution -- Francois Jacob had a paper on this in 1977 called "Evolution and tinkering" and @svalver.bsky.social + colleagues directly refer to tinkering in their papers on tech evolution

Software grows by #tinkering. New modules copy, inherit, and modify old ones. Over time, this creates path-dependent architectures—making legacy systems persistent and hard to refactor. journals.aps.org/pre/abstract...

Real software networks are highly heterogeneous—a few large hubs, many tiny modules. This creates power-law structures that make systems both extensible and fragile. This is why “dependency hell” exists: hubs create symbiosis, but also systemic risk. iopscience.iop.org/article/10.1...
