I've switched as of a few years back and it definitely works like pre-AI/search index degradation for me. But I def understand search is very user specific based on how you search and what you are targeting.
I'm not opposed to video, but if stuff gets lost in the written version that's more a statement on poor exec written communication skills than video being better than text.
People ingest info differently, and being able to communicate the same info in multiple ways should be table stakes at that level.
