The BWB also has the advantage of many more years of study along with a potentially more spacious and flexible interior.
Nevertheless, it is exciting to see research into design alternative to the conventional flying tube and wing configuration.

Still, pretty sure, we will not see them ever as passenger jet (and this is good so).
Just remind, there shall be a pressurized cabin in the wings, with windows at the front edge of the wing.
Just think of a 4 kg goose, which hit the wing at 800 km/h in 8 km altitude, not only the cabin has to be protected, that it will crack and lose pressure, it has also be taken care, that not splinters from the inside of the wing skin will fly around and hit passengers. How thick are the windows of the cockpit, how thick and heavy have to be the windows for the passengers? And how much fun the passengers will have, when the V wing will fly through a nice hail shower. How loud it will be when 3 cm hails will hit the wing, will it damage the hearing of the passengers? The wing has to be armored, additional weight, so heavy, more fuel...
What is the standard crash on airports? The wing is clipping something or someone is driving with stairs against the wing? With passengers inside, it is not any more funny.
Collapse of landing gear e.g., wing is touching the ground.....with passengers inside, not any more so funny.

In many posts the members are lamenting, how boring the standard "tube with wings" design is.
Now comes a new design and suddenly, there are so many reasons, why it can never work. OK it is NIH but you should be happy, that someone thinks out of the box.
It is a feasibility study from an university and far, far away from series production.
And note: Many of the reasons mentioned, why it couldn't work, is dangerous etc. are also valid for a BWB aircraft.
My father still learned at school, that rocket engines can't work outside the atmosphere, because there is no air to push against. Today we know better.
My bet is, that the standard "tube with wings" design with engines below the wings will still be among us for a long time as the standard.
Like the standard cars today have still two axles, four wheels and doors on the sides, like they had in the 1930s. And the vast majority are powered by internal combustion piston engines. The cars and aircraft today don't look like the renderings in "Popular Mechanics" from the 1950s and 1960s. No nuclear powered cars and a/c 60 years later.
So expect no really new a/c design for the next 20 years. Then I'm 83 of age and I don't think beyond that threshold.

At 72, I'm not that far behind you, and feel the same way. But, like with anything else, who knows?

Any legs to it at all?
