[Star Trek] Is Data the only immortal being in Star Fleet?

I'm assuming that B4 would eventually have provided a way for Data to be revived after the events in Nemesis. 

If Data remained in Star Fleet (and didn't go to Cambridge), is it inevitable that sooner or later he would end up running the entire organisation?

If not, what do you think Data would be doing 100 years after the end of TNG? What about 1000 years?

Edit for clarity: I'm curious where Data would end up after huge periods of time. He struggles fitting in with humanity at the moment, but he does make progress, so its fairly logical to assume he would eventually out-grow us. His former friends would inevitably die off, leaving him a bit of a loner. If he did rise to the top of Star Fleet (and eventually he would, unless Star Fleet introduced a discriminating 'no androids' rule) he would pretty much stay there, as he wouldn't die off. Would he be a benevolent dictator, or would we have an 'i, robot' sort of situation?

Alternatively, would he head off and explore space by himself? Would he become a hermit? After several thousand years of putting up with petty humans, would he eventually start to hate humanity? Would he create his own race of androids?

You are coming at this backwards. 

Data's endgame isn't success in Starfleet. 

Most sentients have a childhood and dreams. Some dream of space, and then wind up joining Starfleet. Picard is an example of this. The point is, they joined Starfleet to demonstrate the humanity they already possessed, to make the galaxy a better place generally if only by following their dreams. But there is a distinction between Man and Uniform, they serve in Starfleet but they remain human.

Data joined Starfleet to develop and discover his humanity. For him the rules and structure of Starfleet kept him safe from gross misconduct in the real world while he developed. This is because he didn't have a childhood, or dreams. But in Starfleet he actively seeks to learn from and emulate the behaviour of those who possess qualities he associates with the best of humanity. The point is, he choose Starfleet so that he could be close to the best examples of humanity he had discovered.  For much of his career/life there was no distinction between Man and Uniform for him as there was no Man. At points in time Data even considered forgoing any off duty time as he was capable of serving continuously. 

TLDR: His goal isn't to be the best Starfleet officer and run the show. His goal is to become human. If Data remains in Starfleet forever than he will likely have failed.
