OP are you referring to this site. https://thetokenist.io/news? Can you share the link or source that they did qoute the popularity of BTC over banks.
In my opinion, we are in the era where tech is improving that includes bitcoin technology, yes it can outrun the banks in terms of popularity but that would attributed as investment/speculative commodity. Banks are traditionally used by all countries which are trusted due to its centralization and government accredited. Well decentralized is good but we cant say all our into it. Maybe for now, we cant say what will be few years from now.
