I didn't immediately get the reference. He is the Korean Go player who lost to AlphaGo in 2016.

Why not Kasparov when he lost to Deep Blue though?

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).
