We used to think CAPTCHA was a moat.
"Prove you're human," it said.
Bots would stumble, humans would pass.
Easy win, right?

Fast-forward to 2025:
Attackers aren't hiring cheap labor to solve CAPTCHAs anymore.
They're using AI.
- Solve CAPTCHAs for ~$1 per 1000.
- Crack them in under 10 seconds.
- Bypass even the "smart" ones with logical puzzles.

If you make your CAPTCHA harder to stop the bots...
You also make it harder for your real users.
User friction goes up. Conversions go down.
Lose the battle against bots → you lose users.
Win the battle against bots → you still lose users.

This is the real battle:
Generative AI vs User Friction.
And CAPTCHA is losing — badly.
The answer?
Move beyond static challenges.
Embrace adaptive zero trust architectures.
Use behavioral biometrics to spot real humans by how they move, type, and behave — not what boxes they check.
