People shouldn't assume it is a slam dunk super duper money maker.
Cooling aside, don't forget the infrastructure side of things. Assuming the plan is at least half baked and nothing happens to Bitcoin, this will be a super "super duper money maker".
The first system is tested with gen1 blades and basically just sits there waiting for something more powerful to come up. When AM gets new hardware, they can simply deploy the new boards where the 5000 gen1 blades are now sitting, the doc states they can handle the power and heat. The factory is probably a stone throw away from the farm. They don't even need to touch a power supply or LAN cable. That's how cloud hardware should be built IMHO. If truly mobile, they could populate the farm at a factory and move it to the data center without work being done there. Or just park the container near a power feed and plugin an internet connection. This process can be repeated as many times as needed till the end-game.
Not sure on the 40nm or 28nm specs, but if it would be anything like KNC Jupiter (4 boards per 550GH/s unit?) they'd be replacing more than 5000*10.7Gh/s with over 678,500 GH/s within a matter of days or even hours (assuming they have enough Chinese factory workers to stick 5000 boards into backplanes). They don't even need to install a single power supply or LAN cable, it's already there. Who else could do that, and how? As the document said, "its implications go beyond this simple description". I think the question is not
if it happens, it is
when it happens. For all we know, if the container means anything there could be multiple locations doing the same thing at the same time.
But i get allergic about this noncommunicating behaviour in bitcoin land. Im switching between anger and resigning on this topic. What would i give for securities that consequently communicate even in the later stages...
FC has so far over-delivered not only once. They only sell what they have, they don't hype...
If we force him to spend his time communicating things that may change at a later point, or holding our hands on a daily basis, we are forcing him to give up one of the big advantages that we have.
