I don't think this comment should be so shouted down. Besides the politeness that typically comes with these events, it does feel strange to congratulate, on top of normal politeness, Se-dol's victory.
And for a game that was thought to be many decades away in terms of computer capabilities, this probably should be a time to think of the possible consequences of AI improvement and take a close look at it.
I think (or at least hope) most of the downvotes have nothing to do with congratulations, and only refer to the part where AI is called "an amoral field of study that can potentially delegitimize everything that currently makes humans unique and extraordinary".
That line of reasoning would be worth a laugh, if it wasn't so widespread in the general population.
