I'm sorry, but the "agents" of "agentic AI" is completely different from the original purpose of the World-Wide Web which was to support user agents. User agents are used directly by users—aka browsers. API access came later, but even then it was often directed by user activity…and otherwise quite normally rate-limited or paywalled.
The idea that now every web server must comply with servicing an insane number of automated bots doing god-knows-what without users even understanding what's happening a lot of the time, or without the consent of content owners to have all their IP scraped into massive training datasets is, well, asinine.
That's not the web we built, that's not the web we signed up for; and yes, we will take drastic measures to block your ass.
