Vocational training is a wash if industries change to meet market demands, which they always are. Your IBM mainframe certificate doesn't mean shit in 2017, neither does the 6 week course you took on Microsoft Access if the job doesn't call for it.
Same thing applies to bootcamps. In 2-4 years, the frameworks and concepts you've learned to implement web apps will have changed. In ten, it will be an entirely different game.
