What's unscientific about falsifiability?

It's nonfalsifiable but not for the reason you think :)

I think they're referring to the philosopher Karl Popper's notion of 'falsifiability', the idea that a claim must be possible to proven false to be admissible in a scientific theory.[1] http://en.wikipedia.org/wiki/Falsifiability

It's not science until it can be falsified. Until then, it's merely a speculation.

Is it scientific? I can't see how it can be falsified, it seems more like an assertion than a hypothesis?

Is Karl Popper's theory on falsifiability as a scientific criterion itself falsifiable?
