Unfortunately, any project to drain the supervolcano's energy will meet with immense resistance from various groups of humans with limited intelligence who don't realize its power and the extinction-level destruction its explosion will cause. The article lists at least two ways of safely extracting the supervolcano's power without risking the triggering of an explosion, but this won't be enough to convince the idiotic naysayers. By harnessing its energy, we can have clean energy for millennia.
So it's limited intelligence to read an article that states "But drilling into a supervolcano does not come without certain risks. Namely triggering the eruption you’re intending to prevent."? They state that it could cause an eruption, yes they have an idea for how to minimize the risk but that doesn't mean no risk. As much as we may not like it, some people don't like taking risks at all. They'd rather do nothing and take their chances than take a risk.
