In 2025, too many congratulated themselves on AI progress using the wrong measures. Lines of code added. Pull requests opened. Teams saying they âfeel faster.â Those are activity metrics that we long considered junk. They are easy to inflate, easy to celebrate, and largely meaningless.

MVP programs are elite marketing. Get customers to do your product marketing for free, reward them with status, make them reapply yearly, call it âcommunity.â Microsoft perfected it. Snowflake and Databricks are just running the modern remix.

Calling it a âknowledge graphâ was a mistake and it grinds the gears of the epistemologist in me. Knowledge is factive. These systems store claims, not truth. We shouldâve called them something weaker like information graphs.
