I wish there's someone like GeoHot to be back into JB scene. He is good at physically tearing down stuff and look for exploit (bootrom). Most of the current JB stuff works around what he discovered. The current dev-team is more like a software hack team which can be patched by Apple. I love what the dev team is doing now but it will just be harder to find exploit in software in long term. We need someone who is good at discovering bootrom exploit.
