He's framing Apple marketing as "it's so exciting that we can help people so much", but it's honest and actually true.
The best videos of Jobs are the rare internal ones.
Also, he's 25 in this video? wtf
I suppose I am not surprised by that — that's what marketing does.
The bicycle analogy looks particularly transparent though: there's a pseudo-intellectual aspect to it, even name-dropping "Scientific American" seems to be there to make the speaker appear well-read, a deep thinker.
It works though a lot better than his electric motor analogy that he lead off with. ;-)
Perhaps the training to prepare for these appearances made his moment at Macworld taking on the 'Mr. Jobs' question a thousand times easier, but still in that moment was a critical one - a public challenge - and Steve knew how to move that whole conversation back from himself to supporting his team, which was brilliant, because everyone wants to feel they have someone fighting for them... especially when the landscape/future is squishy and uncertain.
What was this? I've never heard of it.
This was a public performance for Jobs, of course he'd have thought through and rehearsed what he was going to say. His ability to weave together the rehearsed with the improvised - like when his remote broke on stage at WWDC - is one of the things that took him to the next level. Just like the comic who can handle a heckle and get back to their set in such a smooth way you can't even see the join.
