That's not true, at least a lot of the time. Watch an episode of Paw Patrol, go see the latest Marvel movie or listen to number 6 or 7 on the top 40 charts.

A huge amount of what we consider "creative" endeavours that only a human can produce have nothing to do with meaning or experience and are simply a group of people trying to create something that "sounds right" or looks cool, or in the case of a lot of kid's content, merely inoffensive to the largest segment of society possible.

I'm not saying that GPT is going to win the Pulitzer Prize any time soon, but the line between "human text has meaning, machine text doesn't" is quite blurry and process-dependent.
