I don't doubt that they are working on some amazing things, but the big question is are they amazing enough for people to drop elite dangerous or no mans sky and just line up to buy the game.... or will it just be another space sim with "oh this one has this awesome feature but that one has that awesome feature". Not saying there isn't room for multiple space sims out there but the chances that this becomes THE space sim seem pretty low especially as time goes on and on. the things you mention (which I have no clue about by the way) could be stolen, copied, they could lose vital programmers who may move off to other projects, etc.... also you already mentioned that elite D is working on similar elements so people may enjoy them even without advanced options, so that is also the risk of putting so much into features, the average gamer may or may not appreciate the depth and complexity you put in. they may simply say elite D solution is fun and "good enough".
I have great hopes that I will spend years playing this as the original wing commanders, but sometimes less is more, I am worried there will be altogether too much of everything and not enough core gameplay, fun, etc... And also that they have tried to do too much at once.
Ok let me show you a difference between Elite and SC.
In Elite you are ship, you fly with it, you land with it on the station, you switch to buggy to drive on barren planets. At the end of the year, you will be able to do all this stuff with 3 of your friends in one ship. This wont probably change for at least a year.
In Star Citizen though, you can get to a small ship, then fly to hangar of bigger ship where there are your friends.
You leave your ship, walk up to your friends and take a sit (or not) and then all of you go to a station or a beacon.
On this station or a beacon you encounter damaged ship. With your friends you walk through the door to space and the fly in your suit (like on video below) to this ship

On ships there are hostiles and the gravity is turned off. You fight in zero G with hostiles.
You then fix the ship and take it yourself, while rest of your friends get back to previous ship.
Then you decide to go to planet surface on the system.
On this planet you get into the buggy or a tank and explore surroundings. When you encounters Vandull's base you attack it, from any angle you want.
All of that is promised to be possible at the end of this year.
To how complex it is just think about that they have solar systems that have million kilometers and their biggest ships are bigger than three Battlefield maps. Those ships moves in those solar systems in multiplayer environment.
On those ships you can have other big ships and dozens of players running around doing stuff.
No imagine that two of those ships meet and start to fight between each other. Compare that to any other game you know
NMS is a singleplayer game, so its not comparable to Elite or SC.

You cannot just steal some code and apply it to other engine.
You cannot transfer few engineers and then quite fast replicate complex systems, because they need to be integrated into core modules of the engine. Also all assets need to work with those systems.
