“The web” should not first and foremost protect anonymity. It should do what humans need it to do ideally while keeping users private and secure. If there’s a concern, my browser should ask me if I’m willing to share potentially sensitive information with a product or service. I fucking hate this weird angsty idea that the web is only designed for anonymous blobs and trolls.
Letting advertisers identify you through some web accessible GPUs interface so they can track your every move and sell the data to all comers … won’t help you fight anonymous online trolls.
