Regardless of how this "new financial paradigm" plays out, there's a few things I'm certain about:
1. The majority of changes will benefit corporations, not consumers.
2. Middle men won't be removed from the equation, but they'll be replaced by different Middle men.
3. Likewise, some annoying things like cc apr might go away, but they'll just be replaced by new annoying things, like purchase tracking and some form of "gas" fees (just examples).
Always kind of amusing seeing plebs (including myself here) optimistically discussing the future when it's

going to be a "meet the new boss: same as the old boss" scenario.
Best you can do is try to get out ahead of the changes and turn a little profit before you get fucked in the ass by the new guy.
