if you are very high up the chain like Linus, i think doing vibe coding gives you more feedback than any average dev. So they are having a positive feedback loop.
For most of us vibe coding gives 0 advantage. Our software will just sit there and get no views and producing it faster means nothing. In fact, it just scares us that some exec is gonna look at this and write us for low performance because they saw someone do the same thing we are doing in 2 days instead of 4.
Except that Linus does basically zero programming these days. He's a manager, combining code from the subsystem managers below him into a final release.
Less a 'chain' or hierarchy than a lecture hall with cliques. Many of the 'influencers', media personalities, infamous, famous, anyone with a recognizable name - for the most part - was introduced to the tsunami wave of [new tech] at the same time. They may come with advantages, but it's how they get back to the 'top' (for your chain) vs. staying up there.
