That sounds awfully nihilistic. I think you get it right that computers and the internet are misrepresented as non-partisan arbiters of truth (giving rise to absurd ideas like e.g. that machine learning is the answer to all the problems of society and justice), and it should be considered more as a tool. But then you say that computers are worthless and basically we’d be better off without them, when really what you then describe is the capitalist implementation of media on the internet where ad revenue and minimum liability is the only thing optimized for.
You aren’t going to beat the right wings attack on epistemology by telling people not to trust anything they see on the internet. No, you can only beat the right wing by using every tool in your disposal to organize the left and to fight the right.
