Personally I believe the three main causes of Romes downfall were more aggressive warrior nomads assaulting and taking over the territory of the nomadic tribes to their West,and “domino theory like” they in turn were forced to attack the tribes to THEIR West and so on until it impinged on the Roman empires borders.(I have no cite but it may have been because of an out break of the “Black Death” on the Mongolian plains.)
They had I believe a technological superiority over the Romans in that they had stirrups and composite bows ,but I might be wrong on that one.

Not so much technological superiority as superior tactics on the part of the Huns. Even the late Roman legions were more trained for set-piece infantry battles, not against the light cavalry skirmish tactics used by tribes like the Huns. More importantly, though, was the mobility that the legions lacked. Raiders into the Empire could strike where they willed, whereas the defenders were constrained in how quickly they could respond. The later Empire had reduced funding for its military, but more territory to defend. The outcome of that was rather inevitable, no matter whether they faced attackers with stirrups or without.

Secondly the succession system for the emperors was basically based on luck and violence .
So there was as such ,no loyalty to Rome itself but merely an allegiance to your personal “Mafia Boss”,so internicine struggles would carry on right up to (and sometimes beyond ) a barbarian invasion.

This occurred in the succession from the very beginning of the Empire, and on into the Byzantine Empire much after the fall. You may as well attribute the fall to “bad luck”.

I think the last ,and possibly the most important reason for Romes decline was,after centuries of relying on slave labour the Romans ,even without slaves had lost the knack of innovation in agriculture,industry and trade.
The first known steam engine was invented by Hero of Alexandria but was used only as a toy because there wasn’t any need for it in an abundant "free"manpower economy.
My own belief is that Romes legacy of slavery dragged them down in the end ,the sins of the fathers …

By the downfall of the western empire, slavery was pretty much a dead business. It was too expensive, when cheaper alternatives for labor existed – leading to the serf system. And it’s pointless to say that romans had lost the knack of innovation because of slavery – slavery was present in the Roman culture throughout its period of innovation, as it was present in nearly every other conteporary culture.
Although I’m of the opinion that much of Rome’s “innovation” was in more effectively using the innovations of other (slave-owning) cultures.
Hero’s aeolipile is irrelevant, here. Even had there been a need for industrialization, the infrastructure and support technology to exploit steam power wouldn’t be around for many centuries to come. It remained a toy because that’s all they could use it for.
