Docker has made most mocking nonsensical considering how easy it is now to use the real thing... But I would disagree with the premise of mocking as being non-starter. Often times you want to unit test and don't really care if you're using the real "thing" but want to hit code that's got zero to do with that dependency. Good example, we use Okta to authenticate... We want to run unit tests that test how a component in our UI works within our application, we mock Okta to get around our authentication for testing that very thing. When we want to test authentication with Okta, that's what we do.
