The DARPA Heliplane was supposed to cruise at 640 km with a rotor so the idea isn't completely crazy.  It used tip jets rather than a transmission for turning the rotor and had a pivoting mast to reduce rotor drag in cruise. 
"DARPA Hard"  It ain't what it use to be.

 I wonder if you mashed this up with the LightningStrike and assuming you could harvest electricity from the jet turbines, you might have a decent concept.

Did a genetic algorithm make this?

The long pole in the tent for this concept is the propulsion. Back in the day, GE did some work on 'convertible' engines, namely on a TF-34.
There's quite a few reports on the NTRS. It's not easy to do, and would need quite a bit of effort.
All modern aircraft have four dimensions: span, length, height and politics.   TSR.2 got the first three right - Sir Sydney Camm

Kamov has lost to Mil' Blackhawski 400+ km/h less radical contender.

Is that the same Mil design, with the pusher prop at the end of the tail boom?  The one shown for several years at the Russian Helicopter Show?

Is there more information about Mil's winning design?

It does make one curious - doesn't it?

I'll bet it doesn't have a giant wing and canard.

No. Looks like S-67 on steroids (and yes, it has giant wing). No propulsor AFAIK.

I think this is a SBV helicopter from Mil

This does seem a logical progression from Mi-24/35
