On how the NSA can be generations ahead

Tyler D asked about how the NSA could be so far ahead. Besides their ability to make 2" sq. chips at 10% yield (not something a commercial entity could get away with) they can also *thin and glue* those chips into say stacks of 5 thinned die. 2" sq = 4 x performance 5 thinned die with GHz vias = 20 x performance. Both are uneconomical but feasible. Get it? Any questions? ----- all your burst-mode wall-chair-molding-bugs in the state dept are belong to us...
