In user studies it was found that beginner/novice coders (or really, users that aren't SWEs) autocompletion was the most requested feature for improvement in IDE support. It's foundational for understanding what they can write and making sure it's valid.
And that makes sense to me, if you have a lot of experience in a codebase and ecosystem it's not as important. If you don't then typing `.` and seeing a bunch of aptly named methods show up, then snippet completion for their arguments to tab through them, you are immediately productive. Autocomplete turns known unknowns into known knowns.
My org requires screenshots and/or gifs in the PR. Tooling is great, but not everything needs automation all the time when a little bit of manual work needs to be done anyway.
Media companies have been using the value of "content you want to watch" to subsidize "content you don't know you want to watch" for about a century now, the back catalogs are what will keep you paying but that only retains value so long as new content can be added to it.
What is stupid about it? It makes a lot of sense given how programming languages work.
