the meme would only be accurate if what Hegel was doing was saying "imagine some sort of metal thing that makes other metal things go fast" and then Marx and Engels made a gun.
Seriously Hegels contribution to marxism is hugely overstated, almost everything he wrote on philosophy was nonsense and everything he wrote on natural philosophy was wrong, he only really contributed idealist dialectics and that was so under-cooked that Marx and Engels spent a whole book making the idea good, while dunking on him and similar idealist.
