The article concludes that online dating is good for society because it increases the rate of interracial marriage. Isn't online dating changing more than just the rate of interracial marriage?

Dynamite, heroin, chemical weapons, fossil fuels, and refrigeration have all been argued to be good for society due to some single inherent positive effect. They all have negative effects that were unforeseen. If we want to know what the effect would be, we would need to conduct scientific experiments and see the results.
