This isn't true, modern chess engines look at far fewer positions than Deep Blue did. >From wikipedia <https://en.wikipedia.org/wiki/Computer_chess>: "Chess engines continue to improve. In 2009, chess engines running on slower hardware have reached the grandmaster level. A mobile phone won a category 6 tournament with a performance rating 2898: chess engine Hiarcs 13 running inside Pocket Fritz 4 on the mobile phone HTC Touch HD won the Copa Mercosur tournament in Buenos Aires, Argentina with 9 wins and 1 draw on August 4–14, 2009.[20] Pocket Fritz 4 searches fewer than 20,000 positions per second.[21] This is in contrast to supercomputers such as Deep Blue that searched 200 million positions per second." >From Quora <https://www.quora.com/How-does-Deep-Blues-playing-strength-and-algorithms-compare-to-modern-chess-engines-eg-Houdini/answer/Andrew-Ng-4>: " In such, it could calculate 200 million moves per second. This raw, brute-force approach made Deep Blue such a challenge to Kasparov. Today, the strength of engines like Deep Fritz, Houdini, and Rybka is rooted in the software rather than the dedicated chess hardware. These engines are far more efficient, using specialized heuristics to evaluate far less moves than Deep Blue, but to a greater depth of variation. For comparison, a decent personal computer running Rybka can evaluate up to 8 million moves per second" I agree that Google is likely to move on but AlphaGo is by no means the final word in computer go. I'm excited to see the developments that will be required to make a program with the same strength possible on your phone.
