I think it's absolutely ridiculous that there is an attitude here that something is inferior because it is short.
It's a sketch of an analogy to make transhuman/posthuman activism more appealing to a small subset of the population: gamers who don't yet think it sounds pretty nifty. It seems more open thready than discussiony to me.
Let's say you recently purchased a new computer game. Reviewers like the game, but they say that the game itself pales in comparison to a massive, difficult-to-access secret area near the end. Bizarrely, this secret area contains over 90% of the content in the game. It's also rumored to be a lot better designed.
If you're like most gamers, you'll probably play through the game normally a few times, and go for the secret area on your second or third try. But what if the game was real life, and you died as soon as your first try ended?
Edit for clarifying points:
