Like the other poster said, a lot of it is survivorship bias. There are tons of stuff that people did 1000 years ago that have just been discarded through time by being clearly ridiculous/wrong. We mostly never even hear about them anymore. Think of all the stuff people did and acted upon in the past based on superstition or baseless beliefs that was just passed on, but today has about a zero chance of being taken seriously if it were to be brought up.

And continue that thought and think for a minute about all of the hopeless stupid stuff our generation believes in that the next generations toss.
