Agreed. My reasoning:
1) Experience. I've seen so many terrible performance issues because of ORM-centric programming. Talking pages that take tens of seconds or a couple minutes(!) to load when they should take under 5s.
2) Ditto on the "ORMs apparently encourage people to write terrible schemas" observation.
3) "Database-agnostic" (not strictly an ORM thing and not required for an ORM, but strongly associated with ORMs) is a bad idea at least 90% of the time (I suspect more like 99%) it's applied. I've seen codebases replaced atop databases several times. I've yet to see a database replaced on an actual, live product. Moreover, your "database-agnostic" code means it's absolute hell to write any code that touches the DB that doesn't use your main codebase as an intermediary, especially if it's written in another language. That's crippling for your liberty to Move Fast and leverage the data you have, if you're thinking in terms of the business and a product suite rather than a single software product. Use your database. Let it do the work. Your customers will thank you for faster feature delivery ("Oh no, we can't use that feature in this database that immediately and perfectly solves this problem, because that would lock us in to it"), better response times, and lower chances of data loss or corruption.
4) Object-per-table isn't technically the only way to operate in ORMs, but boy is it sure treated that way in-the-wild, more often than not. You want your DB schema and your object hierarchy to be nonsense? Have I got the technology for you!
5) For the tedious cases where you do actually just want to map a select to an object and then write "row.save()" or whatever instead of a SQL statement... that's so easy to write. For the single-table cases it's trivial to write something highly re-usable, even. There, now you have much of the day-to-day benefit of an ORM with 1% of the fat and tech debt.
And re: TypeORM, in particular—I entirely do not get the appeal. It's like some kind of obfuscation engine for both SQL and the intent of the code itself, in a way no other ORM I've seen is. What the hell.
