This is what I think of it.
1. It looks like it has a hydrofoil on the bottom. Hydrofoils work good for surfboards in hawaii. But they are terrible for ships and planes. Hydrofoils were tested in hawaii back around the 1960s or 1970s. They spent most of their time in drydock due to the oceans in hawaii being too rough and putting too much stress on the foils. The foil blades will definitely take a beating here and it will translate to higher maintenance and upkeep, on a component that is completely unnecessary.
2. The wings have moving parts and tilt up/down. Moving parts on stressed structural components like wings translates to greatly increased maintenance and upkeep costs. The US militaries osprey tilt wing rotor is one of the prime examples of this issue. Tilt wing is also completely unnecessary
3. The engines are mounted too close together. There hasn't been a propeller aircraft with engines mounted that closely together built in almost 100 years. Placing propellers too close together, cancels thrust. The vortex of wind that trails the propeller, will clash with the vortex next to it. And they will actually cancel each other out to some degree.
4. There is no need for 8 engines, or special wing designs to generate lift. They're not lifting anything especially heavy. Only a few passengers and whatever cargo they can fit on the small frame.
5. What is needed is stability in crosswinds. Ocean water cooling for lithium batteries. A hull resistant to barnacles and ocean worms. Retractable landing gear allowing it to touch down normally on runway if needed. Fast charge time and good charging options near slip berths. Non toxic building materials. Etcetera.
6. They could have taken existing seaplanes. Stripped the fossil fuel engines out. Replaced them with electric motors. Renovate the interior with passenger seats and windows. It probably would have ended up being much more affordable, reliable. And overall better.
