I would generally agree, but Marx saw capitalism being overthrown by a worker revolution, first violently but later he changed his mind as universal suffrage became more widespread. However, the working class has never shown any interest in overthrowing capitalism, preferring to agitate for a bigger slice of the capitalist cake.
Marx could never understand this, and was constantly disappointed that the working class turned down any opportunity to overthrow capitalism.
The reason I’m careful about trying to predict what will follow capitalism is to avoid having too rigid a programme, which can be counter productive. Perhaps we ought to look more closely at nudge economics.
