The radio was funded by early backers who believed it would be the ideal device for delivering sermons to rural farmers. Viagra was clinically tested as a drug for heart disease. The internet was invented as a disaster-proof communications backup. Very few great ideas start out headed toward the greatness they eventually achieve. That means that projecting what harm may come from a technology before it “is” is almost impossible.
