Ah. I mean, those factors are bad for developers, power users, and/or normal users, but I don’t think they contribute to a lack of understanding of how computers work. It’s that people don’t ever have to interact with or understand the layer beneath the applications they use. That’s not a sign of bad UI, it’s actually a sign of good UI, but without proper education (the biggest factor imo) it does cause a lack of understanding. Ideally we’d live in a world where you don’t need to understand the underlying technology, but it is easy to do so.
