AlphaGo’s victory over World Champion Lee Sedol made a (seemingly) deep impression on me at the time.
I had just NOT expected that. I had expected the game to remain intractable for decades. But the initial excitement and mild sense of doom that followed soon faded. I’m not a computer scientist, just a civilian interested for philosophical reasons.
But many people in attendance at the Alan Turing centenary celebration were World Champions of computer science. And either none of them knew any better, or if any did, or even suspected. Then, it seems that any suspicion that humans would be, uh, defeated at go, in the next decade, was defeated by subtle snickering and mild peer pressure.
Hopefully, AGI is at least “90 years” out.
