CAPTCHAs have failed for 20 years

The article argues that traditional CAPTCHAs have become obsolete as automated agents have evolved to bypass them. It suggests that the future of web security lies in verifying 'agent identity' rather than testing for human-like behavior.
Why it matters
This shift reflects the broader evolution of internet security as AI-driven bots become increasingly sophisticated and indistinguishable from human users.
TL;DR: Every CAPTCHA generation (distorted text, harder text, image grids) was eventually beaten by machines. Now with everyone using agents to run real workflows, the game has changed from testing what a browser can do to verifying who it is. That s why Browserbase is building agent identity with Verified and Web Bot Auth , because the best CAPTCHA “solver” never sees a CAPTCHA at all.
The piece is an industry-focused analysis of security trends, though it promotes a specific company's approach.
