„Gulliver’s travels” was not meant for children:
Despite the depth and subtlety of the book, as well as frequent off-colour and black humour, it is often classified as a children’s story because of the popularity of the Lilliput section (frequently bowdlerised) as a book for children.
The trouble is, in today’s world, even texts meant to be read by adults need to be made so that children can read them.
The culture in the world is vast. One cannot simply know a lot of things, so if you go into a lot of details, or present something deeply, you might not be understood by everyone.
Even a reference like „Star wars” or „Lord of the rings” or „Harry Potter” or „Game of Thrones” might not be understood by some people.
Also, people tend not to think that deeply when they are bombarded with information. If you present something with a deep logic, that is fine, some people might get it, but don’t be surprised if not everyone is on the same page.
For reasons like these, if I were to do a Presentation, I would assume that I’m talking with a beginner audience in my field, not an advanced one.
If I’m sure I can present something interesting, special, or funny, or if I’m talking to an advanced audience, I can go more advanced/deep/specific in my presentation but not make this a general rule.
It’s a dance, and you need to know how to be elegant and fun.
