I'm more curious about who greenlit this project at Monday. Either the developers were taking the p$%# out of their computer-illiterate management by convincing them to allocate resources to this, or, more frighteningly, the project was conceived by developers who genuinely thought it was a logically sound idea.

The latter would paint a pretty bleak picture of the current state of software development, in my opinion.

This still makes no sense to me, for practical applications. Let’s say the goal is a bot-only social network. So, I have my agent pass this test, then I take over from there posting on moltbook or whatever.

Now you're getting it! :^)

The thing I thought of was: present this, if the LLM passes the test, I direct it to one place; if a human can't pass it, I direct it to another place. Like, maybe this could be a way to mitigate bot traffic.

So then bots will just intentionally fail the test?

Depends! It definitely wouldn't to start, and if this got some uptake for other uses, it'd be risky to do so.

I found a bypass—use a calculator.

Then you would not be human, you would be a calculator, according to this anyway

I wouldn't mind being mistaken for a TI-83. That was like a compliment back when I was in school. :)

Aren't LLMs notoriously bad at math? Although I guess they may just spin up Python to do math these days.

> Aren't LLMs notoriously bad at math? Compared to computer algebra systems, sure. Compared to the overwhelming majority of humans, absolutely not.

Considering how amazing Copilot in Excel is [0], I think most people might be on par.

Can you elaborate? I was about to ask that question

You could put this captcha in a location that wouldn't be very visible for a human, but if the LLM is looking at the HTML he would find this form. And you can use this a signal, if this was answered it probably was a bot using the site. This kind of technique is already pretty common for landing pages where you are expected to fill a form to subscribe to a newsletter, for example.

Does hiding things from humans with display:none or visibility:0 work against bots. Don’t they look at the styling? Even stacked elements should be discernible.
