There are rules against using performance enhancing drugs in competitive sports, because ultimately the goal of the sport is entertainment, and the entertainment value increases with a rule based even playing field.

Business is not like this, because the value of what a business does is in its actual output, not in its entertainment value for spectators.

Of course there are other rules (legislative and regulatory) that apply, for other good reasons. But their goal is not to create an entertaining competitive environment, but rather to control externalities of what companies do.

I favor AI regulation, but I also don't think treating it like a performance enhancing drug would be a smart way to regulate it. Higher business productivity is useful to society in a way that breaking home run records is not.
