My initial reaction was what the other person said, but as I was reading theirs I kinda shifted view.

Taking the mystery out of the world doesn't mean we've answered all the questions, it just means our expectation has shifted and we assume that all the dark corners have been explored.
Villages in the most remote parts of the world have Disney T-shirts.
There's no troll under the bridge.
Our stories of the unknown increasingly feature people as the monster.

It's not bad, and there's still wonder in learning about the world around us, it's just a different perspective where the default is a lot more skeptical and assumes there's an answer, even if it's not currently known.

Even conspiracy theories have shifted tone to being more disbelief in rational things than belief in irrational things.
