Not really. I'd say he sees the modern issues we face better than you. It's an issue of echo chambers. If you concentrate a community only with people who share your ideology, especially radical ideology it just amplifies it within that community and achieves little else.
People begin to believe that their worldview is the dominant one, because they're entirely unopposed in their thinking. They are never challenged on any major belief, so the discourse is almost pointless and just spends its time running around the edges of difference.
It also breeds laziness, because you never have to defend your position. Mostly just ends up as communities that share memes with eachother which I shouldn't need to point out is pretty pointless.

Ooh man this one’s gonna piss off a whole lot of people who haven’t read a book in 20 years and don’t otherwise have any information about alternatives to capitalism beyond a vague icky feeling.
You're gonna have to explain a little more about this because on its face I don't see why I should read what a specialist in the philosophy of science has to say about an ideology based on a historical and sociological analysis of the world. They're totally different spheres.
Plus, Marxism is not the entire left, and there's a whole world of thought out there that very likely covers whatever issues you're thinking of.
