Many thanks for sharing your work; I’ll definitely read your book.

I believe that the best ideas emerge from a state of calm, as well as the freedom to explore without the external pressures of grant hunting and its risks. Enjoy!

Demographic shifts, inter-group contact and environmental conditions drive language extinction and diversification.

Many thanks also to @elena-moos.bsky.social, who just joined bsky. Elena was the master knapper in the new study who made the application of the new method possible.

Follow Elena, and I am sure you'll see amazing stone tools (and even dice!) made by her.

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.

Thanks @replicatedtypo.bsky.social for pointing this out.

For a more informal overview of the intuition — including the ecological implications — I also wrote a short Bluesky thread here:

Nice to see “tinkering” being highlighted in cultural evolution.

We recently published a chapter synthesizing our work on tinkering-based models of software and technological evolution.

The growing convergence suggests this idea is now part of our shared toolkit. @culturalevolsoc.bsky.social

Thank you, James.

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

Interesting! Is there any connection between "Top Speed" and "Special Criminal Investigation" (both from Taito)?

Very happy to see our ice-fishing paper on the cover of @science.org this week! 🎣🎉

We tracked large groups of Finnish competitive ice-fishers to study how social foragers use social information when searching for resources. 🐟

In Chaco Canyon in the US Southwest, ancient monumental roads align with the winter solstice sunrise over Mount Taylor. Features of both land and sky were (and still are) ritually important to the region's Indigenous people.

Imagine you have no clue that there is an entire universe of people with diverse capabilities centering on the generation of new ideas and the refinment of old ones.

I dislike that Time Magazine has chosen to conflate CEOs with the people who actually got their hands dirty making the technology work.

I’m incensed that Fei Fei Li is half off the page. I’m sure she is too gracious to say it.

I’d like to thank Stuart Newman for his editorial work in one of my favorite journals these days. Biological Theory is one of the few journals that takes seriously the intersection between empirical and theoretical approaches to biology. I wish the best to Kevin Lala in his new role as editor.

Much of this work was developed during stays at the Santa Fe Institute. It provided a perfect environment to think about technology as an evolving system. It’s an honor to bring these ideas into this classic book series.

Thank you.

This research began years ago when I worked at Ubisoft Barcelona @ubisoft.com. Building Pro Rally 2002 for PlayStation 2/GameCube, I kept wondering whether complexity science could help us understand the challenges of large software projects.

These ideas come from our forthcoming chapter in the @sfiscience.bsky.social volume The Economy as a Complex Evolving System, Part IV:

“The Evolutionary Ecology of Software: Constraints, Innovation, and the AI Disruption.”

The biggest risk perhaps isn’t “AI taking jobs," but the loss of software diversity. If we want innovative tools and resilient #opensource communities, we must treat software as what it is:

A digital ecology shaped by evolutionary forces.
