I Opted Out of AI Training. Does This Reduce My Future Influence?

If we all start opting out of our posts being used for training models, doesn't that reduce the influence of our unique voice and perspectives on those models? Increasingly, the models will be everyone's primary window into the rest of the world. It seems like the people who care the least about these things will be the ones with the most data that ends up training the models' default behavior. Honestly, it's frustrating to me that users of the internet are forced to opt out of artificial intelligence training as the default. Wouldn't it be nice if affirmative consent was the norm for generative AI companies as they scrape the web and any other data repositories they can find to build increasingly larger and larger frontier models?
