You're not the only one, but it can be an unpopular opinion. Of course we wrote very large code bases with no unit tests for decades, before it became a blessed cult of sorts. I know when I've written a method that's so inherently tricky, that I need a unit test for peace of mind. It's rare, and I prefer not to write tricky methods, or complicated architectures. This is practically impossible to avoid on a large team of mixed skill and weak leadership. I prefer not to work on teams like that.
