Another problem not mentioned is censorship. Creation of social bubbles is one of the most harmful effects of profit driven social media. Censorship gives us exactly that whilst maximising profits for the censors.
Left and right are just bubbles, as is Christianity and Islam, black, white, male, female, young, old, and every other conceivable division of humanity.
The Christchurch massacre, for example (one of many) happened as a direct result of this.
I wrote at the time how this was the case, and that things will only get worse as long as we allow it, and here we are now, in something like world war 3, censoring more than ever.
Now the Christchurch massacre, and things like what is happening in Yemen, and Palestine appear to be paling into insignificance, given the attention now on Ukraine, despite literally millions dying in those other wars.
It is a very profound problem, a wicked problem, as articles like mine, and probably yours are included in the censorship, not promoted in the profit driven system, so no-one gets to read them.
How do we even draw attention to it?
