There can be no consent for the usage of your data, as it is impossible to grasp in what ways the data will be used exactly, what deep learning algorithms will learn from it and what impact it will have on your life and society as a whole.

Good. Under GDPR, if there can be no consent, there can be no data.

> some sort of test for users, that verifies that they read the terms of service, as a form of consent for the user agreement.

This will only happen if terms of service get vastly shorter, or if a law is passed that forces it. I would bet that any such measure would absolutely destroy user signup metrics, which means that not only do companies have no financial incentive to take such measures, but they also have an active financial disincentive to make the "I read the TOS, let me sign up now" process any more complicated than they absolutely must.

I'm also pretty sure that the everyday user would be pissed about that additional barrier to entry.

Also, I tried unsuccessfully to convert all those URLs to use HTTPS, but it either failed to connect or the server forced me back to HTTP. That's rather sad.
