Well...as someone who fits into both the category of millennial and employee of a bank, I have to say that the idea of google starting a banking system really piques my interest. I do have a bank account - though not with the bank I work for - but it's really just a place for me to hold cash so I can access it digitally. If I could have all of my financial needs met by a single entity, I would be very pleased. I've dipped my toes into bitcoin and other digital currencies, but none are stable enough for me to feel comfortable with. Banks are great and all, but realistically I'd just as soon keep all my money in a safe under my bed as I would open a new account.
