Presumably a verified click is a click traceable to an attested human identity through your government's soon-to-be-implemented "KYC to use a computer or smartphone" policy.
Oh, you programmed your Arduino to present itself as a mouse via USB, so you can do automated click-fraud that way? No problem, only certified hardware allowed as input devices from now on
I'm not sure what we are going to do about robot arms using touchscreens, or little devices that trick mouse sensors into thinking it's moving. Maybe continuous fingerprint reading?
Heartbeat monitor paired to your mouse's fingerprint readers under the mouse buttons while your webcam verifies your Face ID?
"Approved live human detected: Please spit in DNA analyzer to verify."
Ah, so this is why Anthropic is banning all biological work on it's LLM, it doesn't want you to make an automatic spitting machine to defeat its future ads.
