Sex workers are woke and people with cellphones can access vast amounts of information, including revolutionary theory, that were not available to poor people in prior eras. That's pretty much it. In so far as "lumpen" was a valid category it reflected those people's relationship to information as much as it did their relation to capital. The notion of hopelessly ignorant trash and wastrels preying on the margins of society is not reflected in the technological and informational reality of the 21st century. We can actually reach and educate every single person on the planet with infinitely reproducible digital information now and that changes the math of revolution right down to it's foundations.
