That Idea I Can't Stop Rewriting

No joke, I've rewritten this same story three times now.  I can get three chapters in, tops, before I get frustrated at some nonsensical point and start over.  Send help.


Having advanced far enough in robotics and artificial intelligence, Anon is a volunteer that is downloaded into an android body and sent into deep space with an AI controlled ship to serve as an ambassador to any intelligent civilizations they may encounter.  Due to unforeseen circumstances, Anon crash lands near Ponyville many centuries later, practically resetting him.

The ponies must deal with a childlike Anon that has impossible strength and corrupted memory files.

If you don't care about spoilers, provided I actually write this at some point, read on.  Otherwise, turn back now.

Anon eventually, through either obsession with strange dreams or some other unknown force, is compelled to build a communications array in the mountains of Canterlot.  After doing so, he discovers that his ship has been in orbit, waiting patiently for his return.  While the ship does not contain full backups of his memories, it does contain enough useful information to accomplish his mission.  While not fully understanding the ramifications of this, he agrees to continue his mission after some gentle persuasion from the ship's AI.  The ship sends a transmission back to Earth that will likely take decades, if not centuries, to reach them.

A few days later, the ship reports back that something has shown up on long range scanners and is now headed directly for the planet.  Panic ensues as the mass is big enough to cause significant damage if it crashes at its current speed.

As time goes by, the object becomes clearer and clearer on sensors and is eventually identified as a human vessel of some kind - albeit a massive one.  The ship is a highly advanced battlecruiser turned generational ship after a long forgotten war, and was drawn to the signal by auto-pilot, not any of the crew.  After safely communicating with and instructing the crew, the ship decelerates and lands safely.  Overcrowded humans choose to settle Equestria with Celestia's blessing, and Anon debates leading a mix of humans and ponies back to Earth as he is the only one capable of understanding the ship and teaching others of its capabilities.

Could lead to a PiE story with Luna ruling the new Earth colonies from the Moon once they arrive.

Truth is, I haven't been not-writing these past years, I've been stuck on an infinite loop trying to get the start of this story right.  It's one of those that's going to eat at me too, until I can figure out how I want to get it into an actual story.

I've also been dreading restarting the same story -again-.  I've got enough dead stories on my pastebin, resurrecting this one over and over seems almost cruel to anyone involved, and it's incredibly frustrating to me.  I don't want to return with a half-assing of half of a chapter or something either; I want to have something of substance, something with momentum that I can carry for a while.

Why am I like this?
