Do you realize the blockchain 2 is what Ethereum's exceptional dev team tries to accomplish? You can't seriously think this developer is in the league of Ethereum, his output on the subject certainly doesn't suggests that.
I don't know the Ethereum devs, but why do you assume that he can't be in the same league? None of this is magic; yes, it's complex coding but any competent dev who invests the time can make meaningful contributions to this technology.
Anyhow, believe what you will. I have faith in our dev and I speak from experience.
