If it proves a point at all, it is only that technically speaking it is possible to build an eVTOL in three separate parts viz. a lower and upper quad, with a box in between. The outline of the box is only a question of ergonomics and I've tried standing varieties at half- and full-height, beside seated types that confine the pilot wholly or partially like this. Every iteration is built on lessons from the previous and time itself will prove the most plausible, along with consumer preference. Should one work it is likely that all will, to the extent that whichever form of box might be substituted within the vehicle.
In the meantime, may the best box win...
