I used to think Bitcoin was the future also. I still believe in crypto, but I think a different crypto that isn't out yet will be the future. What would cause people to switch to bitcoin for literally everything? I think the governments would create a crypto well before they let that happen.
Using a government created crypto would totally defeat the purpose. One of the primary strengths of crypto (not just bitcoin) is the decentralized nature. I believe in the concept of a decentralized crypto which isn't attached to a specific country or company. It doesn't have to be bitcoin. The power is in the structure which is a secure platform. Bitcoin just happens to be the biggest one right now.
Google having its own crypto would also defeat the purpose. What happens when they elect a bad CEO or one of their proudcts flops? That will directly effect the value of the currency which is a problem. The same issues arise when currency is attached to a political system. Trump initiates a trade war with China which in turn effects the value of the USD. That is a problem for the currency.
What people want/need is a secure way to exchange value that isn't tied to any government or company. That is what decentralization means. Bitcoin is still volatile as it is still relatively young, however at least the volatility we see with bitcoin is based on actual market activity. The USD will increase/decrease in value because of the federal reserve adjusting the interest rate or printing more money.
There are many angles to it. However, I see all of them favoring some form of decentralized crypto being the future.
