Bitcoin might be of great use for transaction online but still we cannot use it to pay for buying one cheese burger.
Even though there is bitcoin now, fiat money would still be used in the future.
In a perfect world where people are using adopting to things that give them comfort, then bitcoin probably will prevail in just a couple of years. Unfortunately, we live on Earth where people choose to stick with the traditional way of things instead of looking for better options out there
I severely disagree with this approach
What is a perfect world and who is to judge its perfection? Basically, by assuming that people choose to stick to non-optimal options, you are not very far from telling them how to live their lives. You may think that there are better options out there, but how do you know that you are not delusional yourself? For example, later in your post you say that people want to sit in the office for 8 hours just to socialize with other folks. As to me, that's complete bullshit, since they could just as easily walk to Starbucks with their friends instead of sitting in the office and do their online job right there
