Google shuts down Project Mariner

Google has pulled the plug on Project Mariner, an experimental feature designed to perform tasks for you across the web, as reported earlier by Wired’s Maxwell Zeff.

Not super surprised — the “does stuff for you across random websites” part always sounded like herding cats when half the web is popups, logins, and weird one-off flows; did Wired say whether Mariner died because it couldn’t reliably handle those login/paywall/2FA moments or was it more of a “we’re reallocating for I/O” thing? I might be wrong here.

That “agent across random websites” thing you called out feels like it immediately faceplants on 2FA/CAPTCHA/device-binding stuff—did Wired say anything concrete about whether Mariner got killed for reliability/abuse risk versus just being a “reallocating for I/O” decision? I could be wrong here.

Idk if Wired had anything more specific than the “reallocating resources” PR line, but when you mentioned 2FA/CAPTCHA/device-binding I immediately thought “ok so was Mariner basically just puppeteering your already-logged-in browser session, or was it trying to authenticate fresh like a bot? ” ngl I might be wrong here.
