There are concerns about every form of technology. Nuclear energy. Plastics. Online advertising. Vaccines. But we generally don't take those things seriously until there is proven harm. This could mean waiting until it's too late and a catastrophe has already happened. But that's the risk we take with thousands of things every day.
If YOU take the issue seriously, I'll listen. but there's only so much to be gained from debating the threat posed by something that is not yet part of reality.
