YouTube has been riding it's content momentum for too long. It really needs a change of leadership to continue to innovate. For some searches, it's baffling that the top results are clearly intuitively wrong (e.g. showing videos where dislike to like ratio is very high, compared to clearly better alternatives that you can find if you wade through the results)
Why does everything have to keep innovating? Youtube was fine years ago. People make stuff, I subscribe and watch it. Sure throw in some algorithmic discovery on the side. Bring back dislike count. Other than that I don't care for any innovation. Just keep the lights on.
would you like to remove the ability to add labeled chapters to your videos? would you like to remove browseable transcriptions to videos?
Youtube has a ton of things that it still needs to add, such as embedding multiple audio streams so you can have more than one audio language in the same video (I think they are testing it currently), or being able to better modify a video after you've uploaded it. Adding audio normalization to ads so they are not louder than the video they appear in? Still waiting.
Point is, there is a ton to innovate and I think you are quickly forgetting all those useful features that came in the last 10 years that were't there before
