According to U. S. News and World Report, some students find that a “bootcamp” type of course is a quick way to job. Being involved in higher education where we offer a Master of Science in Engineering Management, I find there is room for many types of programs. Yes, bootcamps seem ideal for retraining or transitioning from one filed to another. On the other hand, we hear from employers all the time that the engineers that get promoted most frequently have two traits: 1.) They are excellent engineers that can mentor other engineers AND 2.) have an understanding of how the business functions. That is, they understand how their actions affect the “business” of the organization.
So, I say, yes, their are many valuable educational programs and venues. Not every program is correct for every student.
