By the time the bootcamp junior reaches the senior level he/she would have already accumulated 5+ years of experience. That experience surely negates most benefits gained from a degree.
it's not like the bootcamp grad will still only know one specific stack by the time they reach senior. Any CS knowledge initially lacking should be acquired through experience and self-teaching by then..
Sure, but how many people involved in a day-to-day job of (let's say) supporting a Rails application in their spare time read up on (let's say) data structures, algorithm design, operating systems, game design, database management systems or functional programming?
In an ideal world everyone does this, in reality I found that professional experience is more conducive to growing as a specialist vs growing as a generalist - conversations with coworkers, dealing with bug reports, browsing StackOverflow and attending conferences are all centered around getting deeper, not broader.
