Some stuff just takes time to manual test, e.g. if you provision multiple cloud resources and must coordinate them. Or anything involving some sort of multi step process. If you want to ship quickly, you want a test suite to save you the trouble of doing an hour long of manual test for each change you're adding. Delegating the verification to computer, so that my small team can move faster on the other things we need to build, is a no-brainer. At least, once the "cost to manually test" becomes greater than "cost to implement some tests and setup CI".
