Personally, I'm all for an independent truly democratised global currency. I can see the downsides, but also the benefits. I can see how governments will lose control (if they even had it, since most replicate the independent banking model), but at the same time, it would trigger solutions to a lot of the problems currently experienced by most western societies.
For example, an independent currency requires a government to find new ways of "financing" governmental services. This of course will likely trigger a better service model. Politics might become more streamlined because of this. Banks no longer get a blank check to create and move virtual money at will, wrecking the economy in the process. They finally need to operate like most other businesses.
There is of course a very important aspect to it: what determines the value of a digital currency? Is it the artificial scarcity of computational limits? That's a dangerous proposition to be honest. If the introduction of quantum computing or some other new computingparadigm instantly changes the scarcity limits overnight?
What if we could attach that currency to productivity resources (e.g. dollar - oil)? That's a coupling that always made perfect sense to me. Clearly, the value of money then is in the potential productivity you manage with those resources. This is entirely different from say backing your money with precious gems like diamonds, which doesn't seem as relevant in terms of both productivity and survival.
What then if we finally manage to introduce a workable solution regarding renewable energy? Would a coupling still make sense then?
But most of all: is it reasonable (or even safe) to let a facebook provide such a currency?
These tech giants suck up all technology resources (including programmers and other techies etc.). If they then introduce a tech currency - which is what it basically is, and not an oil currency for example - what does that mean to the global society. How does this translate to services offered to the needy and tech illiterates?
I'm fine with bitcoin, as a standard and maybe as a technology. I'm fine with people offering services around the bitcoin, or the ledger. This is innovation. Techgiants offering bitcoin wallets? Fine, but techgiants introducing a whole new currency?
What do you people think?
