This just proves the point more than anything, really.

Both the website's design and the games presented look indistinguishable from every other AI-generated website and game I've seen in the past. I do not feel any sense of individuality while looking at them, they could've been prompted by just about anyone. Even the little text blurbs are plain unfiltered Claudeslop ("no spoilers, just green and red squares").

Any one of your son's peers could create something identical by typing "claude, make me a cool website with some games" and waiting an hour or two, and that's the problem. How do you think he would feel if he showed this to one of his friends, hoping to impress them, and one day later, that same friend approached him and said "look, I made a website exactly like yours, it was so easy"?
