The thesis that intellectual activity will disappear due to AI is similar to the flawed logic people use against taxing billionaires. "If you tax billionaires, then no one is going to want to work hard!"

In reality, we are programmed to compete and produce and climb the social hierarchy. Intellectual achievement and its use as a delineator in society is not going away anytime soon. Your blog post is active, living proof of this.

It's just shifting... likely to more and more things that signal "hey, this was definitely not produced by AI" such as the lack of capitalization of sentences which has caught on.
