From all POV is a total nonsense.

• we already have a shit ton of gold enough for all industrial demand as material
• gold is just a shiny material
• the amount of energy required to do that stupid transmutation it could be used for something else, more necessary
• this was just a laboratory experiment and all the predictions are based on a mathematical extrapolation, not real case. So it remain just as a speculation

People are really dumb believing these crap articles that feed their greed.
