Sam, this exec BS doesn't look good on you. If Qi Lu is the "one of the most impressive technologiest" you have known then I would say you can be impressed pretty easily. Qi Lu is the guy who couldn't do a squat with Yahoo so he jumped ship to Microsoft. His main achievement there was to rename their product to "Bing". Finally not getting anywhere for almost a decade, he finally got pushed out and so he jumped on the Baidu train to get dip in to Chinese internet boom. Again no special achievements whatsoever at Baidu and virtually everything he touched was half assed and pure PR vaporware. You also have to remember this guy is not
technologist. He doesn't write code, do design or understand modern software architecture. He is a suit which big multinationals need for a public face, sales and marketing purposes.
So let's be honest here. YC needs to tap in to Chinese market's booming startup scene. You can't do that without having native Chinese guy leading these effort. You ideally need a suit who has network and hopefully also understands the little details, you know, like code. But you got only the suit who has network. You will try to do best with what you got. That we get it.
