You get it. 1 tier is better than 2 tier. Python can't be 1 tier, unless it loads the full dataset which is not generally feasible for production online inference cases. PostgresML is 1 tier, and supports the traditional Python use cases.

Why can't Python be 1 tier? It's a general-purpose, extensible language. It can do anything that PostgreSQL can do.
