To counter my last link, here’s Chris Dixon:

But the most exciting aspect of Bitcoin (and this is admittedly more speculative) are all the interesting new business and technology models that “programmable money” could enable. For example, I am very bullish on micropayments (this is a longer topic which I plan to write about separately). The world recently ran its first large-scale micropayments experiment – so called in-app payments on iOS and Android – and despite some serious design flaws (centralized control, 30% fees), it was a smashing success. I think Bitcoin could enable a micropayment system for the open web, and thereby provide a business model beyond banner ads for many important services such as journalism.

I’m not claiming that Bitcoin (or any new technology) can save the economy or the world. The technology industry is in the business of creating products and services that either enable new activities or make existing activities less expensive. Venture capitalists are in the business of funding entrepreneurs who run experiments to try to create these new products and services. I believe the only way the technology industry can offer meaningfully improved financial services is by building new services that don’t depend on incumbent companies. Bitcoin is a serious proposal for dramatically improving the payments industry. There are plenty of open questions but I think it’s an experiment worth running.

This is the best argument for Bitcoin that I’ve read yet.
