## AI overview

The article explains why teams building AI applications should evaluate database concurrency, consistency, and scaling characteristics at the greenfield stage. It argues that PostgreSQL compatibility does not necessarily provide horizontal scaling, while AI workloads can create unusually high concurrency through fan-out across tools, APIs, and databases.

## Source excerpt

The database you choose at the start of an AI project is the one you'll be living with, or paying to escape, for years.
