Scientific Socialism and Technological Socialism

It is unclear if the term "scientific socialism", formulated by Engels, accurately applies to Marxism.  For, the 'science' to which he refers is Dialectical Materialism, the Marxist concept of History.  But History always ends at the present moment, so any concept of it is an interpretation of the world.  In contrast, to change the world in accordance with the principles of an interpretation of the world entails the application of them to action, or, in other words, Techne.  So, more accurate than "scientific socialism" in the case of Marxism is 'technological socialism'.
