I think a big part of it is that the "young founders" are naive and don't know what they don't know. This allows them to strike out in unexpected directions and try things that no one with experience would actually do. Usually, they will fail, simply winding up older and wiser. Occasionally, however, they will succeed, possibly through nothing other than luck, and that makes them look like a genius. Now, I don't mean to belittle the inexperienced young founders; we were all inexperienced once. Also, a few of them probably truly are visionary geniuses (but I suspect most are not). All that said, many of the start-ups I hear about sound ridiculous to me, and most will fail. The few that are destined to truly succeed, however, probably will also sound ridiculous to me. And perhaps, that is why "young founders" are occasionally going to change the world.
