Google Banks is something that scares me... A LOT. I use almost all of their services because I love them, but I don't think that I would go for a bank account as well.

Still, I don't think it's really fair to compare Google or Amazon with startus like Transferwise or GoCardless

They know where you are, who do you talk to, where do you work... and now, they will know all your finances.

Scary!
