It's very dangerous to use the term 'never' when it comes to technology and innovation because things can change in a blink of an eye. Take the adoption of mobile phones for instance. Check out this video from 1999 (https://www.youtube.com/watch?v=aag1P4OwA3s). At the time nobody would've thought they would need a mobile phone, let alone use it. Less than two decades later practically everybody has a mobile phone and a big majority has a smartphone. Funny how sentiment can change so rapidly. And the same can apply for bitcoin. We only need a single catalyst.
I don't like using other technologies as an example of how Bitcoin can be mass adopted, such comparisons absolutely ignore all the details. Mobile phones have disrupted regular phones and now are disrupting desktop computers because they can be carried with you all the time, that's their main innovation. Bitcoin's main innovation is financial sovereignty, and I'm arguing that it isn't as valuable in modern society as most people think. I'm kinda libertarian and most people I've talked to believe that government is the only way society can work, that it brings good and people must obey. Similarly, most people are okay with banks, so I don't see how would they suddenly change their opinion and start using Bitcoin.
