I guess the way I think about it is that because there is/will be such a vast amount of information available that no human will have the ability to do much more than scratch the surface of even what interests them. Much less all the stuff that they haven't even considered might interest them.
I don't really mind that stuff is sifted for me. I still maintain the choice to click or ignore.
Often I am amused by what something thinks I want to see. Other times I am grateful for revealing to me to something that I likely would never have stumbled across myself.
What would, and to an extent does concern me, is the possibility of information being hidden from me or somehow censored.
I don't envision an internet future where the ability to define and refine your search for information will be usurped by machines completely. Unless that is something that you choose. I just envision machines making it easier to find what you might be looking for.
But then what the heck do I know?
