what has this guy done in codeing, maths or logic?

I have yet to find much about his abilities beyond getting people behind him

Not saying that is not a serious skill

but no so much in actually building the product.

Its sorta showing now as in the whole stable of DAO Eth not one of the programmers saw the bug (or did they)

same question raised here in more detail...
https://www.reddit.com/r/ethereum/comments/4opjov/the_bug_which_the_dao_hacker_exploited_was_not/

so eth have used a bolt on high level language .... this is likely to be riddled with exploits. JavaScript like which is so loosely defined its great to run anything anywhere, but as long as you don't mid restarting your browser every so often.

Mission critical not so much.

this is sorta the feel I got, and perhaps counter party forced eth to release early .... but in any even Vitilaik, is not the guy who know inmho, who he needs as coders, and what code is and does, not does he seem to have the mathematical power to undertake proofs etc. I hope I am wrong. He seems like a spokesperson, so maybe he should be CCO chief communications officer of something, but a CEO of a contracts with billions of $ on a unstoppable distributed computer needs a grade 1 + coder / mathematician / computer scientist/ computer engineer, so tjhey can personally sort through the bullshit and choose the right codeing team and approach.
