I presented our work on the influence of AI substitution on creative industry and knowledge production: arxiv.org/abs/2602.03541 and hopefully will see this fun crowd again at @ehbea2026.bsky.social in Leiden soon!

Strong group boundaries, institutions, and norms can act as a safeguard against long-run cultural decline.

We show that in a population with mixed strategies, AI substitution wins with higher efficiency, at the cost of a reduction in group variance.

Glad to see this paper finally came out. Do we still have the opportunity to do research like this?

When we can't have perfect measures in social science, this is what we usually do and should be careful about: https://selfmademodeler.wordpress.com/2024/09/24/how-to-validate-your-model-emprically-part-1/24 Sep 2024 19:52 +0000at://did:plc:jpkockzibia7y2qb2vtgmcys/app.bsky.feed.post/3l4wfgvyuwk2c
