Yes, well their project an idea is not projected to the "now" but to the future. Hitters XU makes some intersting comparasions in his presentation of Nebulas at Global Blockchain Summit in Shanghai from aug 2017.

He is comparing the internet 1.0 as the internet in 1997, internet 2.0 as internet in 2007 and internet 3.0 as internet in 2017 talking about the number of apps and users. He made an analogy between internet and blockchain considering Bitcoin - Blockchain 1.0, Ethereum (with the smart contracts ) - Blockchain 2.0 and Nebulas being the Blockchain 3.0 with the search engine.

Of course these comparasion might be exaggerated but I really believe in his vision.

A trillion dollar market will create a truly large value chain with relevant services
