I searched for my YouTube username and then for the exact title of one video I posted and it didn't find either one.... instead it said the title of my video was not true because it didn't interpret it correctly (but it didn't link to the video).
This is exactly why I built https://www.askyoutube.ai. It helps you figure out if a video has the answer you want before you spend time watching it. It does this by aggregating information from multiple videos in one-go.
I don't think it completely replaces watching videos in some cases but it definitely helps you skip the fluff and even guides you to the right point in the video.
