You still "find most stuff by building/struggling". You just move up stack.

> there will be a shift when all of these vibe code only folks get cooked in a way that's closer to existential than benign

For those who are "vibe code only", perhaps. But it's no different than the "coding bootcamp only" developers who never really learned to think holistically. Or the folks who learned the bare minimum to get those sweet dotcom boom dollars back in the day, and then had to return to selling cars when it call came crashing down.

The winners have been, and will always be, those who can think bigger. The ones today who already know how to build from scratch but then find the superpower is in architecture, not syntax, and suddenly find themselves 10x more productive.
