John Mann and other "spiritual" nuts
"Scientism", as you call it has provided you with the ability to type messages and have anyone with internet access anywhere in the world to read it. Books can be written about all the things "scientism" makes possible for everyone to benefit from, including religious nuts. Give me something from religion that can be used as the basis to improve the material world.
Religion can only improve the life of those who prefer fantasy over reality. I am quite Ok with that. I just wouldn't rely on those people to bring innovation to improve our lives, even keep us alive. They provide HOPE, a meaningless word in a world that requires real solutions.
