According to research done by NN Group, and as per answers in similar existing questions , generally carousels are implemented in a manner that is not very user friendly. The problem with carousels (whether auto-scrolling or not) is that it's very easy for content to be missed by the user.
One of the few appropriate uses for carousels are when you are displaying multiple units of content that all belong to the same category, or in scenarios where missing a carousel item does not hamper the main message of the page. An example of this is when Apple shows off some sample apps in a carousel on their iPad page. The message is that the iPad has access to apps, and if you browse through the items in the carousel, you will see more of those sample apps. This implementation is usable because even if you miss the secondary carousel items (additional sample apps), you still understand the main message which is that the iPad has access to apps.
In contrast, if you're showcasing content on a homepage, putting the top three stories in a carousel is a bad idea because it's very easy for users to miss them. Why run the risk of having users miss out on them? For content sites, it's preferable to have correctly written headlines and thumbnails that are easy to scan at a glance.
