Most money has been digital for decades. It's rare that I actually use paper money or any other physically tradable asset for goods.
Bitcoin is different, but it's not a great system for digital money. Digital USD is way better and there are other cryptocurrencies that also do it better, if you're just trying to get away from the current financial system.
You are new and you have still much to learn.
I'm a bit worried though that even people who made it to this forum do think like this and they don't understand that the way the central-bank based currencies are designed and used by the banks is against the benefit of common people. USD already has the inflation. A central-bank issued digital USD will (most probably) also have the options for surveillance (full tracking) and seizing (if they want to, they can get your money). They are not a way to go away from the current system, they are a way to keep you in even deeper.
I was not trying to make a case for central-bank based currencies as much as I was trying to debunk the OP's title and post.
I am all for the separation of the federal reserve and the ability for citizens to obtain goods with currencies, I just don't think Bitcoin is the answer for any of that; it is a great poster child and has served to really bolster the adoption of cryptocurrencies, but like I said, there are many better options now.
And to infer that "digital money" was somehow created by or originated with Bitcoin is silly - it's the first cryptocurrency, but it's not the first, last, or best digital money.
Hope that clarifies my stance and intent. :-)
