This paragraph rubbed me the wrong way too.

> work that could be done efficiently by the RDBMS the RDBMS? You're only using one? Why not spread the work out a little? Even if you think you write all your queries efficiently, nothing stops your teammates from DOS'ing your efficient queries by writing inefficient queries themselves. Last week our team started started piling up write timeouts because another team was modifying one of their tables. Not in their db, in the db.

> Queries become much more convoluted Please, every ounce of effort invested in ORMs like EF/LINQ is to make code look less like querying and more like plain old object access. For the most part, devs want to work with objects and store objects. If you didn't go the RDBMS route, you wouldn't need EF/LINQs help in decomposing your objects and scattering their parts into separate tables. The least convoluted query possible is to just grab the object you wanted directly.
