The AI Brain Drain

The AI brain drain is the sustained migration of AI researchers from public institutions — universities, government labs, publicly funded research centers — to private companies, particularly the dominant AI firms. Mazzucato's framework identifies this migration as a compounding institutional failure. At the 2023 Algorithmic Rents Research Showcase, she contrasted the early history of AI research where most researchers were at public institutions like DARPA, with current AI research, where most researchers are in the private sector, attributing the migration to higher incomes in the private sector, which in turn come from extractive rents (bad), not profits (good). The migration is not primarily about private companies doing better science — foundational breakthroughs continue to emerge from academic work — but about compensation packages funded by platform rents drawing talent away from the institutions that trained the researchers and sustained the field through its commercially unviable decades.
