I'm aware that there are people that dispute the validity of the scientific method. Nonetheless, scientific progress continues.
For similar reasons, I think tools like this that help automate and improve our normal cognitive processes will be useful to human progress, even if not everyone will use them or even if they abuse them to create echo chambers.
I don't view this as a mechanism where its success or failure rests solely on its ability to achieve universal consensus of opinion. I'm not that naive about human nature. And in some areas I don't think we even have enough information to reasonably achieve consensus of opinion, unless maybe the consensus opinion is "we can't be sure".
