> For example, it would be interesting to incorporate Ghost Font into CAPTCHA systems, as most systems are easily solved by AI today.

It seems to me like it should be easy enough to take Ghost Font, apply normal video compression techniques, and analyze the compressed signal to recover the visual outline of the letters, which you would then analyze with OCR (or an AI I guess ...). In other words, a novel CAPTCHA technique but not necessarily "fundamentally more difficult" than existing CAPTCHA techniques, once the cat-and-mouse game gets going.

I.e. there’s an ffmpeg incantation out there to do it.

Yes, it may be useful to replace current CAPTCHA, but this does not provide the positive side-effects of CAPTCHA where user-submitted data is used to train the unknown images or reinforce the labelling of existing image segments.

It’s been years since captcha was contributing to labeling.

		Indeed, they don't contribute to labeling. The self driving companies figured out long ago that machine learning is way too expensive. Instead, Google is using its large network of willing humans to inform automated driving decisions in real time. So the next time you're asked to click the pictures with the bicycles or traffic lights? Please do so before it's too late. (/s, if that's necessary)
