You are right that it's a huge field, but I'm not saying that we should be familiar with all of it. I'm saying that since we rely on software every day, there are a few concepts that every person should understand on a basic level. That knowledge would help them make better decisions and probably the world would be better if most people had it. Software developers should also understand those few concepts, but perhaps on a bit deeper level than an average person would.
A person can have privacy without knowing what SPI is, but it's very unlikely for them have it or keep it long term if they don't know what Free Software is. What you do requires deep knowledge of the hardware, which an average person doesn't need to have. But they should know what cryptocurrencies and AI are, since those technologies are slowly becoming a part of our lives.
I don't blame average people or software engineers for not knowing those things. But I think something went wrong in our society if people don't understand very important concepts that impact our daily lives and which are mostly decades old. This proves that we can't keep up with modern technology even on a basic level. Don't you think that's bad?
