It feels that point is undermined when the accelerationists don’t succeed and only make a new equilibrium of killing the kid and replacing him.

It feels to me more like a critique that change is impossible.

While the effectiveness of the Accelerationist is questionable, it still introduces the third option of "doing something".

I don't think the story is trying to say "change is impossible", but rather that your only options aren't "status quo" or "leave".
