I hope it’s an UL
Not sure about the visibility for the pilot. Wish he would be located in the front part of that cabin. A bit noisy too, right in front of the engine, but hey, maybe it’s electric
We’ll all find out soon

I will hope that it’s not, it would be far too limited in a UL certification (especially when talking about incorporating new technologies and design of a multiseat-aircraft family).
Anyway, the pictured registry does not hint towards a UL certification.
Do flying wings offer aerodynamic advantages?
Looks more like a VariEze without the canard than the Horten flying wing. This one has vertical stabs.

Maybe, but only if you have the flight computer and movable surfaces of an eagle or albatross or something. Looks cool though.
Could this be certified without airbus-style dual redundant computers? It would instantly go out of control if the computer failed, presumably.
My understanding is that you often get very narrow CoG limits.
There are flying wings with good handling characteristics e.g. hang gliders but you often have to sacrifice efficiency to get acceptable flying characteristics, so lose some of the aerodynamic advantages you might expect.
I saw this fly a few years ago, built in 1943 and I believe still flying. It was quite interesting to see.

Yes, you can develop a stable flying wing. You don’t gain much performance, though. If anything.

The short answer is no, if you let evolution alone to decide all of them will be dead and you will end up with something like a TB/SR20
On metal structures, the only reason we see them is the low radar signature (but then you need a heck of computer to help you fly )
But with that design you can do some serious aeros (+8G/-4G on wood structure is not bad)

Yes. But if you want to design a flying wing that is stable, then probably you will loose any advantage due to the way you’re going to take to obtain stability. If, additionally, you put two BIG vertical stabs at the wingtips, forget it
It can be good marketing though. I’m just remembering one of the anecdotes of Jan Roskam in his book Airplane War Stories, when the director of C172 marketing wanted to add a swept tail. Roskam analyzed the change during a week and concluded that the swept fin will be really bad in terms of additional drag, increased weight and general loose of performance. But probably it will enhance the look of the aircraft.
The next 172 had a swept tail and sales increased by 30%.
