Why not Goliath when he lost to David's new-fangled technology?

Wikipedia[1] says Deep Blue had 30x 120Mhz CPUs and 480 custom VLSI chess chips, and could do 11 GFLOPS. HN[2] says that's roughly an iPhone 5s.

Wikipedia[2] says 11 GFLOPS of compute power cost about half a billion inflation-adjusted dollars in the mid 1980s when the Deep Blue project was started; cost about half a million in 1996 when it was playing Kasparov; costs about 12 cents today. (Of course it's daft to compare custom chess chips and CPUs and GPUs, supercomputers and mobile SoCs, but it'll do).
