At the end of the day bitcoin is just a digital currency that you can use the same way you use any other digital form of currency. They don't need to know any more about the technology itself just as they use a hundred different technologies (from their fridge to the car they drive) that they have no idea how they work.
Therefore, as much as possible those of us who already have a little knowledge of how Bitcoin works should be able to explain to them with simpler concepts but do not omit the original procedure. For example, as I said earlier, it is related to daily activities in real life. You can use gold, valuables at home and things that we can actually illustrate as examples of how Bitcoin works (either in terms of transaction tools or investment assets).
Because after all, explaining in full will only give birth to even more difficult questions. I don't think this is too difficult to convey. I have discussed several times with people both intellectuals and ordinary people who really want to know more about Bitcoin. Of course, the main thing we need to think about is the discussion material that has been adapted to the intellectual level of the audience.
