Not all ideas will make sense to all people, all the time. That’s to be expected, but if your idea doesn’t make sense to your audience then you have a problem.
There are a number of tactics you might want to engage with:
Use the understanding your customers already have, and transfer it to your product.
Provide high quality information to those that are curious enough or inspired enough to seek it.
Educate those that you’d like to buy into your idea.
Don’t loose sight of the likelihood that, if your customers don’t understand your product, you are probably either - selling unethically, or just not selling at all.
Customer understanding is paramount. Understanding your customer base will ultimately lead you to understanding at what level your customer needs information. Your niche geeks will want detailed specs - they need to know how fast it is, how big it is, what it’s made out of, all the dimensions et cetera. Your late joiners just need to know that it has a word processor installed.
The key thing is try, or in other words - care.
