hCaptcha is a service for preventing bots to access the site.
But is this only a purpose of this service?
I think there is additional hidden purpose which is Machine Learning. Training a Neural Network. Tensorflow etc.
Look there is hundreds sites using this and hundreds of people which fill thousands of hCaptcha everyday.
They will be stupid if they will not use it to machine learning.

One of the proof is that
hCaptcha challenges are harder and harder and no more user friendly.

Here are only examples that I found on the net.
But I saw much much harder which was very hard for me to fill.

Why captchas are getting harder

 

I fucking hate the ones in the last example! Who's idea was it to take pics of receipts and use them for captcha?! You can almost never read them even if you are holding them yourself!

 

This is very interesting. And fucked up ofc.
From experience I know since a while ago the Captchas aren't verified or even supervised by a human. You have to solve them wrong many times.

So when in doubt literally what I do is solve them like "what a lame-ass IA bot would do?". This applies especially to the objects that show only a little in one square.

Didn't know the training thing but it makes a lot of sense.
