One of the Marx's points, afaik, is that industrial and post industrial capitalism is always aiming to reduce the cost of labor through technology. Communism would occur when such a diminutive amount of people could produce most of value that communism was the only solution (the actual mechanism is more complicated, I think, but I think the simplification is helpful). Sound familiar?
A bit although I'm not sure it pans out that way in practice. When tech allows humans to produce enough to eat with 1% of the population rather than 70% the others the figure they need cars/SUVs which didn't exist before and now manufacturing is mostly outsourced people become social media consultants that didn't exist before and so on.
Marx always lent towards let's divide people into two groups called workers and exploiters the group 1 can overthrow/kill 2 and install some ghastly dictatorship, which seems an iffy way to go to me.
Marx mostly didn't do that afaik. His followers did. But he didn't write about a dictatorship of the proletariat being violent, or killing lots of people.
