> There is nothing more soul sucking than writing, maintaining, modifying, and supporting ETL to produce data that you yourself never get to use or consume. Instead, give people end-to-end ownership of the work they produce (autonomy).

I think this is more the point than “engineers shouldn’t write ETL”: the engineering-related department consuming the ETL’s output should likely be the ones writing/maintaining it. Or, perhaps more generally: don’t delegate entirely to another team if the team that cares about the result is capable of meeting their own needs.
