When using an ORM you already have to be good at both for any nontrivial query.

My impression is people use ORM not because they lack SQL skills (which is possible), but because it makes object-mapping much easier and with a large count of tables and ever-evolving database, at some point it just feels more natural to drop writing SQL queries and rely solely on the ORM to build up your object graph.

I actually find myself on crosspath where I did start with just SQL but now the database has grown a lot and it is just too much effort to keep writing queries as features pile up. Switching to ORM in one take would be nearly impossible but probably it could work as a step-by-step process, so have both SQL and ORM. Still thinking about this.

That’s up to each user, no?
