I was responding to a comment which said, essentially, that you will end up with lots of forks that are each strong in some particular way. This is not generally how it works in my experience. In general, the fork with (for example) better ease of use will also be the one with better speed because it will get much more time and attention than other forks.
I have to believe "These variants can fill various niches, such as security, speed, or ease of use" and "many will succeed" were also there for a reason, and those are what I was responding to. My point is that for most projects, you don't end up with a bunch of viable forks. It's rare even to end up with two viable public forks, much less several. It's not much like sexual reproduction because sexual reproduction requires there to be multiple breeding entities.
