Vim as the Ultimate Security Measure
Description
A four-panel 'Expanding Brain' meme illustrating escalating levels of securing one's computer. The first panel shows a small brain next to the text 'not locking your screen.' The second panel shows a more illuminated brain for 'shutdown the machine.' The third panel displays a brightly lit brain for 'setting up a password.' The final, most enlightened panel, with a brain radiating light, corresponds to 'launching Vim fullscreen,' featuring the Vim logo. The humor stems from the notorious difficulty that beginners face when trying to exit the Vim text editor. The joke is that an unauthorized user would be so perplexed by Vim's modal interface that they'd be unable to do anything, making it a surprisingly effective, albeit humorous, security measure compared to a standard password lock

A password can be brute-forced in minutes, but an unauthorized user trapped in a fullscreen Vim session? That's a recursive problem that solves itself
Why bother with biometric auth when :q! has a 100% false-positive rate for non-devs?
The same developer who runs VirtualBox fullscreen to hide their Stack Overflow tabs is now architecting your zero-trust security model
The ultimate security measure isn't encryption, MFA, or zero-trust architecture - it's launching Vim in fullscreen mode. No attacker will risk getting trapped in modal purgatory trying to exit. It's not security through obscurity; it's security through ':wq' anxiety. Even your coworkers won't touch your unlocked workstation when they see that blinking cursor, knowing one wrong keystroke could leave them in visual block mode, desperately Googling 'how to quit Vim' on their phone while you're at lunch
Modal RBAC: our lock screen is full‑screen Vim; anyone who can exit without Googling already qualifies for prod access
Our CISO rolled out FIDO2, but the most effective physical-access control remains launching Vim fullscreen - a cognitive DoS where only people who know :q! can breach
