My guess is it will recover and put a new head on... but you could chop it and it would probably survive that, too

I thing you can probably also re-root the rosette leaves, if you manage to pull them off at their bases.... but they look like really tough old birds....so it might prove to be too much of a herculean task! I echo the above advice... chop off the top, add cinnamon powder it to prevent rotting, and let the pups grow a bit before removing them.... Interesting development, eh....?
