My partner who is an accountant, so intelligent but not technical, watched some Veritasium documentaries the other day.
Her comment was that she was really impressed that it didnt dumb anything down like normal documentaries do. She was able to follow along more technical stuff than she anticipated, and that made her enjoy it even more.
I think we need to give people more credit when it comes to complex or techincal explanations. If people are enjoying the context but dont understand the techincal, they can just gloss over that if they prefer. But I felt this was quite telling at how and why Veritasium is such a popular channel.
