I disagree with this take. I hate learning by video unless it's for physical stuff where seeing it is useful (e.g. how to wire something), and thus I always prefer text content when searching for information (due to the higher flexibility in moving at my own pace instead of the narrator's).
I've never had issues with Google pushing videos too much in search results. You have an initial "videos" results block I just scroll past by, and that's that.
The much bigger issue is the narrowing attention span of people. Thanks to social media, like Twitter, but also Stories, Shorts, Snaps, Reels, TikTok, etc. people's attention span is going down. Many people would prefer watching 10 tiktoks instead of spending 10 minutes reading a blog post.
