Huge point you make that it can be done by non-scientists now. Now we can all play with fire. That much power in idle hands controlled by mediocre minds is like everyone being magical.
It sounds weird, but I believe its meant as "untrained minds".
Yes untrained but more broad to mean people who don't understand the magic, people who are negligent, etc. I kind of got it from Einstein's quote, "Great spirits have always encountered opposition from mediocre minds."
