The Jobs comparison is apt, ego-driven hype man. Love Bill Burr, probably gave best description of Jobs. NSFW (again, Bill Burr), but for those who haven't seen or looking to be amused again here's his take:
As to auto-18 wheelers, I agree big business will do it as soon as it becomes viable. My question is less about their ability to get them from point A to point B, and how they're going to navigate parking lots and backing up/lining up. Feel like being on an interstate is doable (perhaps not now, but soon). The rest, I dunno.
