Wow, I guess now we know where the budget deficit went... Let's ignore
all the consequences apart from cost and see what the budget for this
thing might be. Since you guys are obviously buying in bulk I guess you
can get good memory for say $0.10 per MB (1 GB, or 2^30 bytes of memory,
for $30). You want, eh, 2^35 times that, or about 34 billion 1 GB memory
sticks. So that memory alone should have cost about $3.4 trillion.
That's got to be some computer! ;)
