I find the subject matter interesting, but the article itself seems to be the result of status quo bias. Supporting status quo is different from being neutral.
I also note Twitter is, of course, not neutral. Maybe it is more “politically neutral”, but to state the obvious, Twitter rewards people who are good at writing tweets simply by existing. Similarly, Instagram probably exacerbated lookism and biased the world towards attractives and against unattractives. I am not sure why giving power of influence to people with better tweeting skill or attractive face is any more merit based or fair than status quo.
The article started so well, but it started to go downhill mid-way. This is generally the problem of engineers who despise liberal arts as useless: they try to think of society in objective terms, which is an impossible task due to the inherent subjectivity of the way you look at it. This is something you learn early on at any social science course.
An algorithm that replicates cultural bias is just as political as one that tries to counterbalance it. All algorithms that try to parse society are unavoidably political because everything about society is political.
