Marx couldn’t have predicted the computer revolution, but absolutley predicted how Capital might react to suppress revolution. The US is well past the point at which revolution would have naturally occurred, but because of factionalism, Imperialism, and other methods by which the interests of the Proletariat have been veiled from them have caused Capitalism’s natural death to take on a form of hospice care. Computers managed to bring about revitalization in Capital, only now is it increasingly becoming worse as Capital gains more fuel to entrench itself.
If you seriously think Marx wrote his conclusions before writing, you haven’t read Marx, full-stop.
