Rating the Ten Plotlines

Io9 has a list of Ten plotlines you'll find in science fiction - over and over again:

1. Robots
2. Interstellar Travel
3. Time Travel
4. Superpowers
5. Bodily Transformation
6. Parallel Universe
7. Alien Invasion
8. Immortality
9. The Post-Apocalyptic World
10. Godlike Aliens

I would rate the likelihood of the ten tropes (from most likely to least likely) as follows:

1. Robots
2. Bodily Transformation
3. Immortality
4. Interstellar Travel
5. The Post-Apocalyptic World
6. Godlike Aliens
7. Alien Invasion
8. Superpowers
9. Parallel Universe
10. Time Travel

Parts of the above ordering are trivially obvious. For example, bodily transformation must be more likely than immortality or superpowers because either immortality or superpowers imply bodily transformation. Immortality is almost certainly more likely than interstellar travel because it will probably take longer than a current human lifespan to get from star to star. (This might not apply if it's ETs doing the traveling.) Alien invasion is less likely than interstellar travel, a post-apocalyptic world, or godlike aliens because aliens will need to be godlike to invade at the end of that long a supply line, because anything resembling a successful alien invasion will produce a post-apocalyptic world, and because aliens will need interstellar travel to get here.
