What if the Roman Empire Industrialized? | Alternate History

In today's alternate history scenario we ask what if Rome underwent an Industrial Revolution, managing, under the Good Emperors, to undergo mechanization, urbanization, build the printing press, and use inventions like the Aeolipile by Hero of Alexandria to build steam engines, railways, and steamships. Will Rome maintain stability, or will it collapse and fracture? Can Rome defend against the Persians, the Huns, and the Germanic tribes? Will Rome expand, colonize, or even discover a new world?
