I think over and over, again and again, if the two key technology parts I designed will work..... 

One is a novel functional mechanism, another is a novel network architecture...... 

(1) If the network architecure doesn't work, the system ability will be highly discounted, and one of the three business units will be unrealistic; 

(2) If the functional mechanism doesn't work, but the network architecture work, then at least 1.5 parts of the business units will be impossible and the only 1 or 1.5 parts can work, but the point is that the 1 unit that left over is the most challenging one in the three...... 

(3) If none of them really work, then only a very little bit left that I can do, a novel moble app;

(4) But if both of them work, it might probably be an unprecedented huge business plan (potentially the very best) that any wall street VC has ever seen.

And currently I think both of the two parts will work...... After all, although I'd never write any code, I at least understand "if, then" and what computer can do and cannot do.

It's not really that difficult, just nobody has tried to reimagine the world before. People lives in "status quo".
