It's a depressingly common thing in history that many innovations that have changed the world have either been feared or held back. One of the big problems many institutions such as the church engaged in was guarding knowledge but not sharing it, basically ensuring dependency on them which is also why you saw a significant decrease in folk healers. The printing press was actually criticized because it increased literacy, many fearing it would make a lot of church officials obsolete. It's also why you see coal and gas companies trying to keep green energy from growing despite it being a better investment. They either don't want to relinquish power or they stupidly cling to obsolete ways.
Yeah its always been the same, like how laymen used to perform exorcism until the church wanted the power back. As the power to do an exorcism doesn't come from ordination but from baptism.
Just like with green energy.
Also a bit off topic I know sorry but I'm in shock here,
Adam Deats just spoke to me. he said he liked my Vampire Killer, I can't believe that I feels so lucky.
