Captcha
Explanation
This comic satirizes CAPTCHAs and their escalating difficulty, imagining a future where verification tests become absurdly demanding.
The comic appears to show a progression of increasingly difficult "prove you're human" challenges. What starts as a standard CAPTCHA (identifying images) escalates into more and more elaborate tests. The scenarios depicted show people being subjected to complex philosophical, emotional, or intellectual challenges as a means of human verification, far beyond the simple "click all the traffic lights" tasks we're familiar with.
The joke plays on the real-world trend of CAPTCHAs becoming progressively harder as bots get better at solving them. The comic extrapolates this arms race to its absurd conclusion: if AI keeps improving, the tests required to prove you're human will eventually demand capabilities so sophisticated that they become a burden on the very humans they're designed to verify. The title "captcha-4" (with the number suggesting this is the fourth comic in a series on this theme) reinforces that this is a recurring source of humor for SMBC, reflecting how the CAPTCHA experience keeps getting worse over time.
