A correct machine learning solution for a non-trivial problem is very likely to have higher complexity than a traditional approach known to work. For a toy or hobby problem, all's fair, but for a business application the added complexity can have significant impact on cost, time to market, etc.

Well, I know I don't need to install GPUs on servers I install Postgres on, so there's that cost.

You don’t need GPUs for machine learning.

In fact the majority of tools in this space are exclusively CPU based.
