I saw this cheap hybrid at the ferry a while back.He's piled into something and bent the fork .The fix?-reverse it and keep on riding.The brake still works.If you like your face the way it is,use a steel fork!

Make that 3. Mine just snapped today as I pulled away from some traffic lights on my way to work. Luckily wasn't going fast but took a fair chunk of skin off my left hand

Did you over-tighten the bolt on the top cap? That can do it.
But on the other hand, that's a shocking failure. I hit a speed bump every morning and wonder about that happening......
There is absolutely no way that failure is anything to do with over-tightening the top cap bolt!
To me looking at the enlarged image, it's failed just at the point where the diameter reduces, just above the crown race.

It's a point of weakness, that would be stressed by an over-tightened top cap, maybe contributing to work hardening to the point that the metal became brittle?

I think everyone above has covered all you need, but just wanted to say:
WOW! So glad you're alright - could have been seriously nasty.
As others have said, I wouldn't worry about CF fork. Most aluminium bikes these days seem to come with a CF fork - it's pretty standard. I'm assuming you're not planning on making a habit of riding through big potholes. The only other possible watch-out with CF forks is if you spend a lot of your time with the bike fixed into a turbo trainer (of the type that clamps your front fork in place). If your turbo training often has you out of the saddle putting some big power into the pedals / handlebars, that can put some big strains on the fork.
Good luck with Scott - I hope they'll sort something for you.
Jesus! That is incredible.
Out of interest is there any sign that a "ring" around the snapped area as wore away?
Looks like you need a straight 1 1/8" straight steerer. You should also know the axle to crown distance and the rake. Differences in these will change the geometry and feel of your bike.
That's not ideal! I'd be interested to see what Scott does in this case and if they can help you out with a new fork possibly. You can get replacement carbon forks from the likes of Kinesis which are worth checking out
Holy cr*p that’s scary. Assuming it’s not some dreadful seized bearing grinding through the steerer problem, (I don’t see the crown bearing in the photo, presumably it dropped out when the fork went?) that should be sufficient for Scott to reconsider the scope of the recall.
The fork should not be the first component that breaks in a debate with a pothole. I would expect a snakebite puncture, rim ding, maybe cracked or buckled wheel, before the crown gives way.
The recall notice said they only had one report of failure. Yours makes it two.
Sizes on a new fork - it appears to be straight ( not tapered) so 1”1/8 which is pretty standard will fit. Headset bearings will have the size/angle marked on.
Totally agree with this.
This is a result of the front wheel getting caught in a drain at 35kmh, throwing me a good few metres down the road.

So yes, pursue the maufacturer as this looks like a long term deterioration and probable manufacturing/design problem.
No marks on my helmet either, I conclude that it saved my life.
Canyon48, thank you for the response and the heads up about the recal. Unfortunatly my model is not covered in that recal. I have got in touch with Scott none the less to see if there's anything they can do.
Not a great picture of the break as the bike is sat in a London Evans at the moment. I finished the last 2 miles of a 600 mile charity cycle on a borris bike !!!
Thanks for the Planet X link. I don't know a hell of a lot about fork compatability other thank it needing to be 700cc and rim brake compatable. Is there anything else I need to be aware of ? I'm looking at the Planet X RT-58a Fork.

This isn't true.
I'm amazed you managed to snap an aluminium steerer as well (very glad you managed to stop before anything catastrophic happened!). Out of curiosity, have you got a picture of the snapped tube?
I don't suppose yours is a 2014 model, these were recalled for snapping steerers http://road.cc/content/news/120915-scott-recalls-8000-speedster-bikes
If your bikes serial number is mentioned there, then I'd try your luck going to a Scott dealer and saying you've bought the bike back for the recall and you want the fork changed! If not, they might at least be able to source a replacement fork (though how much it'll cost I don't know).
PlanetX have lots of forks at reasonable prices https://www.planetx.co.uk/c/q/components/forks-and-shocks?sort=price-asc
