ORMs are absolutely fantastic at getting rid of the need for CRUD queries and then boilerplate code for translating a result set to a POCO and vide versa. They also allow you to essentially have a strongly typed database definition. It allows you to trivialise db migrations and versioning, though you must learn the idiosyncrasies.
What they are not for is crafting high performance query code.
It literally cannot result in insurmountable performance issues if you use it for CRUD. It's impossible because the resulting SQL is virtually identical to what you'd write natively.
If you try to create complex queries with ORMs then yes, you're in for a world of hurt and only have yourself to blame.
I don't really understand people who still write basic INSERT statements. To me, it's a complete waste of time and money. And why would you write such basic, fiddly, code yourself? It's a nightmare to maintain that sort of code too whenever you add more properties.
Plenty of tools out here doing plain sql migrations with zero issues.
At my day job everyone gave up on attempting to use the awkward ORM dsl to do migrations and just writes the sql. It’s easier, and faster, and about a dozen times clearer.

Because it’s literally 1 minute, and it’s refreshingly simple. It’s like a little treat! An after dinner mint!
I jest, I’m not out here hand rolling all my stuff. I do often have semi-involved table designs that uphold quite a few constraints and “plain inserts” aren’t super common. Doing it in sql is only marginally more complex than the plain-inserts, but doing them with the ORM was nightmarish.
