Yes.

Depends how you define illuminati, illuminati is just the group of people at the top of the natural hierarchy of dominance so yeah the illuminati will always rule the world, doesn't mean they're all bad people most secret societies started as decent organizations used to uplift and guide the masses into order so they can sustain progress. Most ended up getting corrupted by people with selfish intentions and used as a tool to control the masses for their own gain.

Illuminati is just a term to define the people who have the greatest all round understanding of the human experience, it gives them an edge above the entire world because no one is above them, if they innovate something, they're the only ones who wield it's power. It goes all the way back to the Egyptians and the all seeing eye on top the pyramid(dom-hierarchy). Being at the top is emphasized because it gives you the edge, no one can understand you, but you can understand everyone.

The original "illuminati" secret society that named its self off this concept was full of good people, philosophers, religious scholars, scientists ect.. they were inevitably corrupted over time because that's just what happens to systems and tools that wield power.

You could argue that the military is in the illuminati, who ever is running Q is illuminati for sure. The illuminati is a teir in the dominance hierarchy that's full of dozens of groups, that have an edge over each other in one way or another but all have an equal edge over the teir below.

The work around for this was actually the US legal and Military structure, replace the groups of people with groups of systems, compartmentalized as best it can while still being efficient, and giving the power to the people to elect and oversee who is managing the "illuminati".
