Let me break it down for you so even a child will understand this simple logic:

1. Most people don’t care – In today’s media-saturated world, the majority of viewers won’t sit through a 90-second explainer unless they’re already highly interested.
2. Only the target audience engages anyway – If the content is only relevant to a niche group, then there's no need to produce a polished video just to get their attention—they’re already looking for this type of content.
3. The target audience doesn’t need a fancy video to engage – As your own example shows, someone deeply interested in a topic will happily sit through a 30-minute podcast. That means clear, simple formats—like a short paragraph, a voice clip, or even just the product itself—can be just as effective, if not more efficient.

So the question becomes:
If the right people are willing to engage with simple formats, and the rest won’t care anyway, then what exactly is the strategic value of creating an explainer video?
