Yeah like his labor theory of value has basically been disproven but that doesn’t have to negate his critique of modernity and his view of class conflict, notion of private property, exploitation, etc. Historical materialism is hugely influential even today. Marx didn’t outline some rigid framework for a communist utopia either.

Hegel’s idealism as well… Marx began as a Hegelian in Germany and increasingly became critical of Hegel’s dialectic. His concept of dialectical materialism is a response to Hegel and turns it on it’s head. The notion that material conditions aren’t shaped by human ideas and values but instead that human ideas and values are a response to material conditions.
