The whole "grinding" mentality/culture has instilled unhealthy and unrealistic expectations into the minds of the typical boot camp "candidate". It is difficult to compare a 3-6 months boot camp, with consistent working / learning over 3-5 years.
Sure, some students will learn very fast, but on average - there's more to it than just cramming. And the people that manage to "grind" for N months and land a FAANG job are few and far between, not to mention that they're essentially cramming a very, very small portion of the CS curriculum.
Not to mention that some new CS students are already "heavily invested" in the field and spend a lot of time during their youth around computers. All members of my dev team have been already working in IT during high school. This must be so hard to beat for someone starting late. CS graduate can easily enter the market with 5+ years of experience with actual work.
