Let me recalibrate my understanding.
Every computer will be essentially generating bitcoin. Essentially, it is hyperinflation. However, this distort economic calculation to a really bad level. Everything you invest in looks like a profit, when it's actually not.
There is still no incentive to save, because your saving is becoming worthless every single day due to inflation. Basically, it rewards the biggest generator at the expense of everybody else, except those who borrows money.
In the bitcoin economy, the generators still benefit disapportionately, but it will also benefit those who save. In other words, everybody who save win, except those who borrows money.
Investors in business will be forced to be more conservative or efficient at finding economic opportunity.
There won't be hyperinflation with BitCoin because of the algorithms--the faster BitCoins are generated, the harder they become to generate (and thus require ever more amounts of electricity or hardware). My issues with BitCoin come from the unfairness of money creation, which is essentially a technocratic central bank issuing currency. If you have enough CPU-power and energy, you can originate most significant amount of new BTC into the market. While the rest either hoard it because of its deflation or spend it occasionally because of "time preference." As people deflate BTC into smaller and smaller units, in absolute terms, everyone is playing with "more and more units of currency," the only difference being the zeros are being added on the opposite side of the decimal point. With all of the hype and attention for BitCoin in recent press, it could be heading towards hyperdeflation, where "People postpone buying indefinitely because they expect prices to fall further." In BitCoin, there will be no incentive to spend, which is kind of ironic and self-defeating for a proposed new money.
If I had 50BTC and thought that it would deflate incredibly, I'd be waiting until 0.00005BTC would pay my rent before I'd use it, I'd have a million "units" to play with.
