While some people are hard lined enough on this that I agree it sort of becomes weird, I can tell you my beef with ORMs comes from being burned before a couple of times by a super inefficient aggregation ActiveRecord did on GROUP BY queries that it 1. not only took a really long time to figure out why a particular page in our app was loading slow but 2. we ended up having to write raw SQL to fix it.

I think the answer depends on the type and load/volume of app you're working with combined with the dynamics, size, and skill level of your team(s). I'm extremely comfortable writing, profiling, query planning, and debugging SQL queries. Others aren't, and therefore having an ORM to query data in the DB with the syntax of the language you're using in your projects makes way more sense, if nothing other in order to speed your team up.

I think the mistake is thinking an orm is actually going let you be free of knowing or caring database fundamentals. That only applies in the most simple cases. An orm has other benefits though.
