The inherent nature of the technology industry is that we all always have to be levelling up and finding new ways to create value. The better your ability to reason from first principles, learn new tech, etc. the better you will do.

Teaching people a specific approach and tactical skillset without the underlying fundamentals does not set them up for success in a fast moving industry, particularly right now when we're undergoing an enormous shift on virtually every level. But it _can_ be an accelerant for some people, so I'd never discount a bootcamp grad on the basis of their learning method alone.
