Captchas te not meant to deter all bots. It’s meant to make it ever so slightly expensive that a mass DDOS attack would be extremely expensive to perform. Think like thousand sof requests per second, all being Captcha’d and how much it costs to run AI. It’s current not a feasible solution.
There is cheaper AI that can solve Captchas though, and it’s only gonna get cheaper.
It’s long been cheap enough that you can pay a call center full of people in a developing country to solve them for you. Going to be a while before AI is cheaper than that.
Having used them to protect a few web sites from spammers filling up forms, they do cut down on the bullshit. This makes things more convenient for the people reading the information coming in from those forms, but I sometimes wonder if it’s worth the cost of everyone else having to pick out the bicycles in the picture.
I believe this is why Google, and a few other companies, have started using behavioral analysis to figure out if you are human. Did your mouse wonder around the page before clicking to verify? Did you come from another website as if browsing the web? What device are you using and have you used it on this site before? Are you logged into an account? I’m sure they use many more factors, but it’s something that would be hard to replicate with bot behavior on a consistent basis (for now).
