I'm just agreeing with xyzzy4; finding the game fun is more important than anything else.
Personally, I don't like the fact that luck is a bigger factor that chess players are willing to admit. Sometimes you make a move that anyone would consider strategically good, but little did you know, that move would put you in a bad situation many moves later, and only a machine or maybe a grand master could know it.
While you're right (all ages can play Street Fighter), it's hardly something that one can expect to be common in, say, 45 years. Chess will certainly still be played ubiquitously.
Furthermore, Street Fighter requires good reaction times, hand/eye coordination, etc. A better counter-point might be something like poker (or another card game).
That said, you're right: if you don't find chess (as a game) interesting, you probably shouldn't spend time pursuing it :)
I'm amazed that he also (intuitively) figured out "the French sound" (the linguistic term escapes me) well enough to be able to call out words for not being words. I wouldn't be surprised if many French speakers tried to sneak some high scoring words past him, knowing he can't speak French only to be flabbergasted when he called their bluff.
And by the way, I too thought the reactions needed were insane. But after some time, you realize all that is just muscle memory, and the hard part is the strategy. It's a conversation between two minds.
In fact I don't think many processes in nature are truly random (quantum phenomena have to have a large effect and you need to choose a no-hidden-variable theory), but it doesn't really matter. It's just a model.
