They say it is fast enough not to notice and cheap enough to be the future of ad blockers and content firewalls. I built a browser extension with Jev @typesafeai that can hide/collapse posts on X based on natural language. It's so fast that it's not noticeable and insanely cheap...this must be the future of "ad blockers" and content firewalls. How Jev or TypeSafe is used, in the post's own words: “I built a browser extension with Jev @typesafeai that can hide/collapse posts on X based on natural language.” The post does not name a separate audience.
