It seems that AlphaGo suffers from the horizon effect, meaning that when it is ahead, it becomes blind for wining sequence that starts with an unusual move. It is great that Lee Sedol has won this game, because it shows that humans still have a better understanding of the game. Relying on a mental vocabular for reasoning about the game, has some weaknesses, it might still prove superior when reasoning about very complex situations like the one encountered in this game. It seems that Lee Sedol took most time to think about this move. Later on in the game, AlphaGo, played some bad moves, probably because its winning percentage had dropped.
I am not denying that Git is more powerful than Subversion, but to me it seems much less user-unfriendly and less robust agains commonly made mistakes. I feel Git makes me think much more about what I have done, and is less forgiving for small mistakes, in that sense it often feels like a burden than a support.
After using Git for about a year now, my conclusion is that subversion is good enough for your team, and heaven compared to Git. With subversion you can just peform an update without having to wonder if you might have something that still needs to be commited. I am also not convinced that creating branches and merging all the time is realy a good way of working for the team we are working in. I am getting used to stash, pull, stash pop, and resolve possible merge conflicts, and only commit and push when I am done with my changes. Yes, that sounds very much like working with Git in a subversion manner, but it seems to be the most productive way of working for us.
To get something done, a committee should consist of no more than three persons, two of them absent.
